Logitech QuichCam 9000 webcams not working on Windows 7 64-bit since latest Windows Update patches were installed...
Running Windows 7 64 bit RTM (7600) - clean install. Logitech QuickCam Pro 9000 was initially working using the default drivers from windows update / driver search. A recent Windows update some time between 18th October and 26th October has caused a malfunction.
The webcam no longer gives an image. Applications trying to use the webcam think that its already in use. The problem occures on two very different machines both running the same OS as above.
Installed the latest drivers from Logitech - several times, using varoius compatability options, tried disabling Kaspersky Internet Security 2010 - make no difference. Tried to roll back to onder drivers - they no longer install as they are marked as incompatible.
I have three of these cameras and the only one left working is the one attached to my Mac Mini that I use for iPhone dev work.
I logged a support case with logitech and I figured I should ask some questions here too.
Any ideas anyone as I'm all out of ideas...
