Webcam issue: usbvideo.sys ?
I am running Win 7 RC release. I cannot get any webcams (have tried 3 ) to work properly. In each case the webcam is recognized, latest drivers installed, and all looks well in device manager. In any app using the webcam (live messenger, skype, yahoo messenger etc.) I get the "cannot connect to webcam, already in use" type of message.
I have tried everything -bios upgrade, different cams, different driver versions etc. I am 100% certain that this in an OS issue.
What I do see is that the usbvideo.sys system driver is not running (listed as stopped) - on all my other systems (XP and Vista) it is listed as running. Start mode is set as manual. I am pretty certain this is the issue. What do I need to do to fix this? Is there a way to reinstall usbvideo from the install cd or from a MS download?
Thanks in advance.
