Webcam not detected because USB "Unknown Device" isn't working... "Windows has stopped this device because it has reported problems. (Code 43)"

One of the drivers controlling the device notified the operating system that the device failed in some
manner. For more information about how to diagnose the problem, see the hardware
documentation. On the General Properties tab of the device, click Troubleshoot to start
the troubleshooting wizard.

Check with Toshiba Support, their on-line documentation and drivers, and ask in their forums
about any known issues. This is usually a driver, BIOS, chipset, or hardware issue.

Both of these found issues but were unable to fix them

Hi,

It looks like you have hard drive issues. Run CheckDisk (chkdks /f /r ) in Advanced Mode
or better use the Manufacturer's Diagnostic Utilities or use the  trial versions below.
If the disk issues can be cleared then run sfc /scannow again. If no then you need Toshiba
Support of the help of a real computer shop (one that does its own in-shop service).

------------

For even better and more efficient checking :  <- Advanced Methods.

From the Command Prompt of the Recovery Console (if you have one) or from a Vista/Windows
7 disk - if you do not have a Vista/Windows 7 disk you can borrow a friend's (it needs to be same
32 or 64 bit and they are not copy protected) or make one. Also your System maker will sell the
physical disks cheap since you already own Windows.

chkdsk /f /r

REBOOT

What are the system recovery options in Windows 7?
http://windows.microsoft.com/en-us/windows7/What-are-the-system-recovery-options-in-Windows-7

----------------------------------------------------------------

Go into Setup/Settings (BIOS/CMOS) often F2 as you boot so watch screen as you startup. Set the
boot order to CD/DVD to use Windows disks (Vista or Windows 7 whichever you have installed.)
Remember to set back when done.

If you need to make repair disks - these help repair Windows not re-install.
Often a these disks will help when the OEM Recovery Disk does not.

Download Windows 7 System Recovery Discs - now charging $9.75 for the ISO
images to make the disks. (These can be made on any computer running XP,
Vista, or Window 7 that has a CD/DVD burner.)

Rob Brown - Microsoft MVP <- profile - Windows Expert - Consumer : Bicycle - Mark Twain said it right.

May sound funny but it worked for me, so give it a try and if it works let me know ok?

Right click Computer -> Manage

Go down to Device Manager then right click on the Unknown Device, select Properties.

There are 3 tabs : General , Driver , Details. Click Details.

Under the Property scroll, select Hardware Ids. Now mine said ACPI / TOS6205. Which requires a Bluetooth Stack driver and it sounds irrelevant, but when I found and set up the required driver to fixed that, which means after that there was no Unknown Device problem any longer, my webcam started working.

So again I hope it helps as it helped me, let me know if it was luck or I tapped into the real deal OK.
