It's a usb video device, I also tried to use the class GUID of

0x08, 0x00, 0x2b, 0xe2, 0x09, 0x2f); // image camera
But the result is the same!

If it is truly a USB video class device, then it is designed to be opened
by ksproxy.ax as part of a DirectShow graph, not directly by user-mode
applications. What were you planning to do with this when you got it open?
