If you look at each instance in DevManView and look at the Connected column. You're seeing 3 'instances' of the device - which is OK.

17514 usbvideo.inf USBVideo.NT 01:38:44 a.m.ġ) DevManView shows us the cam is connected and detected and the Windows generic video driver is loaded. Here I add the data obtained with DevManView: so next question, is why is it not?ĭo the apps (like Skype) say no cam found? Or other error message? Or you mean you're just running the app and get a blank / black screen (with no other application error messsages appearing?) That said, I'm guessing your cam didn't come with a CD? And the vendor said all you need to do is plug it in? Those are strong indications it's designed to work with the Windows driver. (On the other hand, Logitech is one of the companies that develops alot of its own hardware specific drivers in order to provide more functionality then what's provided by the the Windows generic video driver) Most simple cam vendors design their cams to work with the Windows driver, so they don't have to develop any driver themselves. Your info tells me your cam is currently using the Windows generic video driver that comes in Win 7. as to the rest of the puzzle, well, will give it my best try.
