Built-In Webcam Not Working - "Unknown Device" USB Code 43
Hello,
I have looked over many, many other forums and threads regarding this issue, but to no avail, have not been able to solve my problem. I'm starting to think that some hardware that communicates with my Webcam could be damaged - but I have not given up hope that this could be solved alternatively.
Here are some of my PC specs:
OS Name Microsoft Windows 7 Professional
Version 6.1.7601 Service Pack 1 Build 7601
Other OS Description Not Available
OS Manufacturer Microsoft Corporation
System Name BRADY-PC
System Manufacturer Hewlett-Packard
System Model HP Pavilion dv3 Notebook PC
System Type x64-based PC
Processor Intel(R) Core(TM)2 Duo CPU T6400 @ 2.00GHz, 2000 Mhz, 2 Core(s), 2 Logical Processor(s)
BIOS Version/Date Hewlett-Packard F.14, 07/01/10
SMBIOS Version 2.4
Windows Directory C:\Windows
System Directory C:\Windows\system32
Boot Device \Device\HarddiskVolume1
Locale United States
Hardware Abstraction Layer Version = "6.1.7601.17514"
My laptop came preinstalled with Windows Vista Home Edition - I have since upgraded. The webcam was functional with both OS. Also, my BIOS is not updated with the most recent available software (F.15 is available). I had F.15 and downgraded to F.14 to see if that might solve my issue, but it did not.
I have tried a variety of different things (clean boot, various installs of the driver, uninstalled all of the devices listed in Universal Serial Bus controllers and restarted), but again, to no avail.
I'm hoping someone might be able to shed light on my problem! I can provide anymore additional information as needed. In the device manager, where it shows "Unknown Device" (which I believe to be the built-in webcam, as it appeared around the same time the webcam stopped working), which is under the Universal Serial Bus controllers, I copied all of the information in the Properties - Details tab. Here is what is displayed for all of the categories:
Any help would be greatly appreciated!
