Generally any USB camera with VendorId 0x46d and ProductId 0x840, 0x850, or 0x870 should work (you can see the Ids by using operating system utilities, for example "lsusb" in Linux). Note that some new Logitech QuickCam Expresses and Labtec cameras are reported not to work which have ProductId 921 or 920. For those cameras here is an experimental driver.
