Hello everybody,
a month ago I bought HP ProBook 4740s. Everything was OK until now. I haven't been playing (or using any 3D apps) for two weeks. Yesterday I wanted to play a game which runs on OpenGL and I wanted to configure its profile in Catalyst. I double-clicked the icon and it immediately crashed. Since that time it has been crashing even when computer was idle, just few moments after I turned it on. Since Catalyst doesn't work I am not able to use 3D apps reasonably.

Windows 8 64bit.
Radeon HD 7650M and Intel 4000HD switchable graphics.

I am getting "Catalyst Control Center: Host application stopped working" message.

Hello, I bought new SSD disc Crucial MX300 2.5-inch SSD (275 GB) for my laptop: HP Probook 4740s.  When I try to boot new Windows 10 system the installation process started to freeze and stopped with Windows 10 logo and preloader icon. I checked disc (it starts when I try live GParted Linux distribution. I can add partition etc.). Do you have any suggestions why Windows does not start to install properly ? Can it be SSD format problem or   SSD disc Crucial MX300 2.5-inch SSD is not good for my laptop ?

Hello! I used my Probook with a 840 evo for years without any problem. Now I got a 850 pro, installed a clean win10, updated it and installed softwares, had to reboot it many times, it was working perfectly.I installed Samsung Magician, switched to performance mode and since i can not boot at all, "no boot device found". The SSD is visible, but even formatting (NTFS with win10 installer) and a new install of win10 could not make it bootable. I thought about hardware failure but the service tested it found no error. The notebook is working fine with any other HDD/SSD. Can it be an incompatibility issue? If yes then how the heck was I able to install and run Win10 before installing Samsung magician? Thanks Zoltán

I installed Driver pack solution 2015 online and in Driver pack it finds the driver but when I press download it says 404 error not found :|.

This is from where I got the driver installing software driver pack:

The "Unknown device" is probably the laptop's IR Receiver. IR is a relatively niche tech that isn't used very often when it comes to laptop communication. Even in it's heyday it was a pain in the *censored*.Also, "Driver search" Style software is useless at best.

From an etaf (Wayne) post:

How to identify hardware in Device Manager

right click on the device with a yellow!

from the menu choose
Click on the Details Tab
Under the Property - drop down
Select hardware ids
Right click and select all
Then right click again and select copy
Copy and paste that information here

You should see a code similar to this


please reply with the full code for your device(s)

The portion of the code highlighted in RED is the Vendor ID and the portion highlighted in GREEN is the Device ID. In this example:


Vendor ID = 8086
Device ID = 008A

Post back those two numbers make sure we know which is vendor ID and which is device ID

These codes can be looked up at this site

As an example the link for that database tells us that;
Vendor ID code 8086 is for this vendor - Intel Corporation
Device ID code 008A is for this device - Intel Centrino Wireless-N1030

Hi. I got a new PC last week and have been putting all my software and hardware on it little by little every day.
I havent been using the PC a lot though, other than to get it all up and running.
It has Windows XP.
Anyway, for the past 2 days in a row I started to use it... and when I would leave it running and be away from the desk for a few hours, I would come back to find a message that Windows has experianced a serious error and do I want to report it to Microsoft. So, I do of course. And the error info I get is that it is an unknown device driver. How can I find out whats causing this?
I ran Windows Update and updated ALL the critical updates and driver updates.
I also thought it could be the system standby mode since it seems to be happening when the PC has been idle for long periods.
Is there a known problem with standby affecting device drivers?
I have no idea where to begin on this. I am new to XP.

  So, I was working in a digital audio workstation while in a Skype call with my friend, and all of the sudden the PC just freezes. I tried to speak, but he couldn't hear me. So, I figured that an audio driver installed with the DAW might've contributed to the problem. I went to the Device Manager and saw two unknown devices in the "Other" category. Yet, I don't know what they are. There's really not so many details or information about the two drivers. There's no manufacturer names, descriptions on what they do, and even more suspiciously, they aren't digitally signed. However, there is interesting values they're set as.  One is ROOT\MEDIA\0001, and the other one is ROOT\MEDIA\0002.  In addition, they don't have the necessary drivers, as I googled "Error 28". In addition, I think these drivers are the culprit of my OS malfunctioning.

I have been having this recurring problem for quite some time now. Every once in a while my computer will just restart itself and come back with an error message saying Windows has recovered from a serious error.

As it restarts it goes to a black screen, not a blue screen, and in the center it says "No Signal" which is highlighted in blue. That is just normal for shutting off or restarting the computer though. Should I change it so it doesn't restart on system or failure to see if I will get a BSOD? To me this seems like some sort of power supply problem or something. Anyway here are the messages I receive when it goes back on:

On an athlon 1900 + xp, could overheating of the cpu, which causes the computer to re-boot, give me an "unknown device driver" error message on re-boot? I have checked and re-checked every driver and can't find an issue there. I have ordered a heavy duty cpu cooler to see if that helps.

I cannot currently get online through wifi or an eithernet cable. In my device manager one iteam is listed as an 'unknown device' and I believe it may be my network driver. Also I get a driver error when trying to connect to my wifi, but I am able to see my wifi and connect to it with my phone. I'm assuming I'll need some sort of driver download, but being as my older phone is the only way I can get in the internet right now it's been hard tracking down what I need. I own a NV57H20u laptop. If someone could link the download for me that would great. Or let me know what I should do instead. Also I've already ran the computer in safe mode with networking and AVG as well as Malwarebytes without any luck.

On the unknown device in Device Manager, right click and select Properties. Under the Details tab select Hardware ID's in the dropdown box. Please copy and paste the first line in your next post.

Hi all.

I'm using an ASUS laptop X53E series running Win7 sp1. I use an Acer 27" external monitor and do not have the laptop monitor on. I noticed an error msg this a.m. indicating that an Unknown Device is missing a driver. I searched in "Unknown Device Properties" -- "Details" -- "Property" -- "Device Instance Path" -- "Value" to figure out what device is being detected. The Value is ROOT\DISPLAY\FSVIDMIR.

I haven't found anything by searching Google, Bing or Tech Support Guy. This "unknown device" was installed six days ago on 8/30/14. I did change the monitor connection from HDMI to a VGA 15 pin cord, but that happened yesterday, not six days ago.

I should also mention that I connected my Samsung Galaxy 3 to a USB port which screwed up my system (I don't remember any of the details) but that was well before 8/30/14. I cannot open TSG SysInfo or I would have included it in this message.

Any ideas, direction, etc.

Thanks in advance,

Larry K

I have been dabbling with a very weird problem since a month back. I can not find a solution to it and it is playing with my laptop ever since

I have acer aspire 4720 running vista home premium.

My problem started when window requested to download and install a driver without indicating the type or the location. I gave the ok and as soon as download

started my Bitdefender total security 2009 interceded and blocked the download this was the first and the last time BD reacted to repeated request and without

permission from me or user account control the download and installation proceeded. Despite the notice popped up by window saying the driver could not be

installed due to lack or resource etc. When I looked at Device manager I saw in the network adapter an entry to unknown device.I looked at the driver
property and it seems to be unknown in name, manufacture and without reference to files for location,however under details it was listed as sw_BDFNDISFMP
and looking for under device instant path it show as Root\ sw_BDfndisfmp\0013. The number 0013 changes to 000 or 0014 every time the darn thing is downloaded without even knowing about it. This only happen just after starting window. When this happens vista becomes very slow to launch any programs or files and at times window explorer freezes. It will take like 5 minutes before system improves a little for me to access Device Manager to uninstall the darn thing and sometime it takes several attempts to get... Read more

A:Error caused by Unknown Device Driver

I was going to quote your question, but it's to long...

Random reboots or Blue screens are a sign that something is wrong as you have reinstalled and changed what you thought was the problem, the video card, then your fault lies elsewhere.

Try removing one of the memory sticks, they can cause errors if one is faulty, if the error occurs, try the other stick, also look at temperature of the board, is the CPU running to hot, is there sufficient cooling for the board, etc.

Remove all items except the video card and 1 stick of memory and work upwards until you get the reboot, as you have changed the video card you know it's not this, unless the motherboard has a fault somewhere in the AGP controller.

You missed one, download them all again and go one by one.
If you're able to extract the actual Driver files directly then just naviate to it from the Device Manager and update.
Things like these are tricky at times and require lots of manual work. Create one folder with all the drivers and start opening them one by one. Then move them over to another fold once you're finishied.
I like to download them and name them what they actually are. Makes it easier to track.

If the Computer is working fine then it is best to disable the pesky device that keeps asking for the driver in the Device Manager.

After that open the Device Manager (Control Panel\All Control Panel Items\System) and send its screen-shot with the unknown device expanded to help in determining what this device is.

Greetings, once again...

This morning, after happily running my Windows 7 Enterprise Computer for 9 months, I was greeted with an "Installing Device Driver", followed by a "Device driver software was not successfully installed". Upon checking for more info, it turns out to be an unknown USB device.

Now, what is interesting is that I have added nothing to the new hardware at all requiring any new installation. Coincidentally, (I don't know if this has anything to do with anything, but also this morning), the DVI side of my dual screen setup wouldn't come on. This may be totally coincidence (I suspect it is), but it is odd that both of these things occurred at the same moment. I fixed that DVI situation. Still the unknown device appears. (I am wondering if Windows rebooted my system last night. I keep the unit on at night to run backups.)

My question is: Is there an easy way to identify which USB device is causing the problem. I have uninstalled the device, unplugged the USB's and re-booted but it always re-appears indicating the device is still plugged in. So, I am looking for some detective work. Is there anyway to identify which USB devices are up and working collectively? Any help would be appreciated.

I have a Toshiba P875-S7200 laptop. I put an Intel 240GB SSD in it, put an untouched Windows 7 x64 on it (using X17-58997.ISO), and activated it with my own COA key.
I got all the missing drivers installed except for one. Using the VEN and DEV #'s from the Hardware ID and going to sites like, etc, I learned what the (vaguely labeled) mystery hardware was, then got the official drivers from
Problem is, this last one labeled Unknown device, has an unusual Hardware ID that looks like this:
I'm reluctant to install any driver software to have it find out but I was wondering about the drivers from The page I'd be getting them from is here. Not knowing which driver I need, I wanted to get all of them, put on a DVD, then point the Device Manager to the disc to hopefully install it.
Is it safe to use the drivers from this site? If I get them and scan them with MBAM, SAS, and Avast, as long as they're clean, are they okay to use? I'm very leary of these things and could use some expert insight here.
If I shouldn't use these drivers, then what should I do about this mystery driver?

need to get more info. there should be a list of hex (00E000BF) blah de blah that would be helpful in diagnosing it. Also, a few things:

1. have you added/removed any hard/software recently?
2. how long has this been going on?
3. Does the blue screen stay up long enough to read? If not, right click my computer, go to advanced, startup and recovery, and make sure that the 'auto reboot' is unticked'.
4. How far in the reboot can you get? Can you get past POST? BIOS? Can you get all the way to windows?

the more ammo, the more likely someone here can kill this problem, to coin an analogy.

I built a new PC July 2005 (please see the specs in signature below) and until about two months ago, it ran without any problems. Then, it began to randomly reboot & still is as of this posting. Sometimes it does so while being used and other times it can be just sitting and not being used with the monitor turned off and it reboots. I have even gotten up in the middle of the night to hear the POST beep and found that it was rebooting. It does tend to reboot more often when not being used and the monitor is turned off than when it is being used. When doing video editing, which is very processor intense during the rendering process, it never reboots.

I have not added any new hardware to the PC and the only software additions or upgrades/updates have been the usual Microsoft updates and patches they send out monthly and the anti-virus definitions and other updates for Norton Systemworks Professional 2005 that come out weekly and sometimes, daily. I have run the diagnostics app that comes bundled with NSW Pro 2005, which stresses the video card, RAM, HDDs, etc. and nothing happens.

For about a couple of weeks the CPU was hovering around 39 to 42 degrees C, but that was just because some of the air vents had gotten stopped up with dust and as soon as I blew them out and vacuumed out the case the temps returned to their normals.

Hi, I'm trying to reinstall my sister's scanner driver because XP has decided that it's not there any more. This happens occasionally and usually reinstalling the driver fixes it (I think that's what I did last time), but this time i just can't get it to work.

If i unplug the USB cable then plug it in again, it comes up with a message saying that the device has malfunctioned and it doesn't recognize it. I have the driver CD but windows always manages to install it as "Unknown device" before i can tell it to search the CD. I've tried telling it to reinstall the driver from the CD but it says that there are "no better matches for this device". I've also tried uninstalling the program form the CD and reinstalling it then restarting the pc but that didn't help either. I tried plugging it into another USB port (as suggested by Windows Help Center) but that still didn't work.

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name

 I've got a HP Probook 450 G3"with Windows 10.Recently I received this note at startup: "Smart Audio. A Conexant audio device could not be found. The application will now exit." Thereafter, Windowns informed me that it did a scan and found a possible solution, for which I need to restart the notebook. This I did, but the same initial message appeared. The speaker icon on the taskbar also still have a red cross next to it. I then download the Audio driver from here: Conexant High-Definition (HD) Audio Driver (American, International it installed, restarted the notebook, but still the initial message appears. I thus do not have any audio and the audio button on the keyboard also doesn't respond to swithing audio on/off. Please help,

Hi I would consider As an adminstrator, in a Command Prompt Window, typegetmacThis will list MAC addresses for those items that are present, and may not be connected.A good number would be 3,1 x Ethernet1 x Wi-Fi1 x Bluetoothand then typeipconfigand in the long list look for named devices have a matching MAC address.Along with Device manager this is a way to determine the number of devices. Device Manager has a VIEW: Show hidden devices, and it may be in there.

It shows two drivers with errors, mobile 4 series express microsoft wddm 1.1.  If I delete them and reboot, they both come back.  The lenovo system update does not recommend a newer video driver, the intel tools don't find it, if I manually download and try to run the win10 one for x64 systems it says it does not meet the minimum system requirements.  Some searching shows it to be a 4500 series type driver so I would think it would have worked.  Any ideas?

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 bit. After the reformat was finished, I ran Windows Update and it found several items to download and install for me. I noticed that it also found optional items to download and install for me, so after all the important updates installed, I ran the optional updates. After all of this installed, I checked Device Manager to see if there were any errors and I found nothing. I assumed everything was fine. I decided to check Devices and Printers and under my laptop icon, there was a yellow icon with an exclamation point on it. I decided to run the troubleshooting option when I right-clicked the gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same icon appeared. When I clicked on the icon a second time, I noticed that the model of my computer at the bottom of this window, changed from L505 to TIAS. I have no idea what this is. I decided to do another reformat on my hard drive. This time, I ignored the optional updates. I checked Devices and Printers again, the same icon appeared but the model of my computer said L505, like it should. There is something in the optional updates that is changing this. Could it be the Intel chipset driver that the optional update is pushing? I'm not sure. I went back to Device Manager, th... Read more

I have Windows 7 Ultimate. Since very recently an unknown device keeps popping up in the device manager every time I start Win. It's reported location is within the front USB root hub but I haven't changed there anything lately. The device status reports "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall/disable it but it will get picked up again the next time I reboot. All other usb devices (mouse, keyboard, web camera, APC UPS, external drive, printer) work fine. How do I get rid of this nuisance so that it doesn't reappear?

Well it might be a good idea to look at the following tutorial:

Use the link in Step 7

Also I tend to find this tool useful:

Right click on each result in the list for more options.

Edit: On my machine a similarly named device appears to be a webcam.

In the list USB Composite Device doesn't mean much but matching the ID seems to indicate that it's the webcam.

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.


A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 header or the motherboard shipped that way and I inadvertently made matters worse. Anyway, that header on the motherboard is without a doubt unusable.
Since I don't really need the USB 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 boots and I plug a device into the front ports of the case, Windows detects the front USB ports as "Unknown Device" within Device Manager yet says the driver is successfully installed. I've already downloaded the most current Intel chipset drivers for my motherboard, deleted and reinstalled all USB drivers, and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 headers on the motherboard, and I've tried plugging in several devices to the front USB ports, and this problem still persists.
I've ensured the connection inside the case is solid, yet I cannot get Windows to recognize the front USB ports.  However, I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via m... Read more

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

Fresh install of Windows 10 and the last driver I need to sort out is the above.

I believe it is my powered USB 3 hub to which I plug in my keyboard and mouse. Technically it is working but I don't like seeing yellow triangles on devices.

So are there any fixes?

A:Unknown USB Device (device descriptor request failed)

If it's a generic USB 2.0 Powered Hub then technically there's should be no drivers needed by Windows, if it's a USB 3.0 Hub then I'm unsure (since I don't own any USB 3.0 Hubs).

Might be a Windows bug, basically Windows can't find the description information to display the Hub's name in the Device Manager example: Generic USB Hub, Root Hub Device, etc....

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".
