Solved Help! My webcam installs a different driver when plugged-in.

September 7, 2015 at 23:56:21
Specs: Windows 7
I have an A4Tech PK-810G webcam. It was working perfectly until yesterday. I used it on Skype and the video is not working but the microphone is. Same with Facebook. I uninstalled the USB root drivers from a clean boot but when I tried to plug-in the webcam, it installs a different driver which is Vimicro USB 2.0 PC Camera (Venus) and is now detected as is. I tried it on different ports but the result is just the same. The problem is, the A4Tech support website doesn't have the driver, as well as the CD the webcam came with (it says it's "driver-free"). Now, I can't use system restore either since the last time I used the webcam is 4 days ago and it's not available on the options. Now, I found out on the web that I'm not the only one who had the same problem. Please read for reference:

I think you're misunderstanding what I asked in # 2. The video stopped working even though you had what you believed were the correct drivers. So you uninstalled the drivers and windows installed different ones. It appears you're saying the webcam is working (not working) exactly the same way with the new drivers as it was after it failed when using the old drivers. That is, it failed when you had the 'correct' drivers installed. If that's true why do you suspect drivers and not a hardware failure with the webcam?

Also you say you uninstalled the 'USB root drivers'. Does that mean you uninstalled the USB port drivers and not the webcam drivers or you uninstalled both or was it just the webcam drivers?

As far as the driver being for a different brand, there could be several reasons:

!) The two brands could be clones and windows is using what it feels is the newest driver.
2) The two companies may have merged and the newer drivers are with the vimicro model.
3) If there was a hardware failure windows may be seeing the webcam differently and installing different drivers.
4) 'Driver free' means a company is satisfied the default windows drivers--which may originate with MS or another manufacturer--will operate its hardware. So MS may have made the update on its own.

Have you tried rolling back the drivers? I know you said you uninstalled them so they may not be there to roll back. But you might check anyway. Here's some info on that if you're not familiar:

Is this the correct driver?

That's the first site I've been to but unfortunately, that file there is not the driver but the webcam software. The "universal driver" on their support page doesn't work either.

Under the old drivers the video stopped working. Do you recall how those drivers were identified in device manager?

With the different drivers installed does it act exactly the same way or are there some differences?

Maybe the drivers are OK but the webcam is bad.

@ DAVEINCAPS
Answer 1:
The drivers were identified as those of A4Tech before this happened.

Answer 2:
OBVIOUSLY, with Windows incorrectly identifying the hardware and installing a different driver, it's not working anymore.

Answer 3:
How can you even say that the drivers are ok, when it's not even of the same brand?

Update: This morning, I tried it on a different PC, with the same OS. Still, it's not correctly identified by Windows and again, it installs the very same driver (Vimicro) instead.
