I can move Logitech up to the top of the list if for the other two "Cameras" I select Properties -> Drivers -> Disable. If I go into Hardware, I get a list of the two Cameras and the Logitech device as listed in the Device Manager. If I select this camera and go to Camera Properties, there are two tabs, General and Hardware. Under "Unspecified" it gives only "Camera" - by default the Camera icon has some sort of alert symbol (I'm working from mobile phone photos of the screen here, I didn't snap that one). Now if I look in Control Panel -> Hardware and Sound -> Devices and Printers, I see a index of icons for Devices, Printers and Faxes, and "Unspecified". I don't know what the first two instances of "Camera" are, but I've confirmed that if I pull the USB camera out of the USB port, the Logitech entry disappears, and reappears when plugged back in. In going to Skype -> Tools -> Options -> Video settings, where I would expect to be able to select the webcam, it says "Skype couldn't find a webcam. I made some headway, but it still isn't working. I'm a Linux man, so not a Windows expert (or even user) by a long shot, although I've had to deal with it at work enough that I had a fighting chance.

I'm trying to help a friend get a Logitech Messenger USB webcam working on her Windows 7 Professional (update 1) system to use with Skype. First ever post on Stack Exchange, although I have been using it for a long time.
