I have bought in China a small USB PC camera (webcam), which came without driver. Windows XP recognizes the PC camera but asks for the driver. Otherwise it cannot work. Until now I could not find it on the internet.
It is a "Webcam with Usd 2.0 interface cmos sensor 1.3 megapixel" from A.M.I. Shenzhen Company (also called HTD or Shenzhen soopen), model TO8 (or QQV8), as described at the following address:

I would very much appreciate if somebody could send me the appropriate driver for this webcam.

My first guess is that this is some knock-off/counterfeit of another product and that you got scammed. I suggest buying a different model from a reputable manufacturer that offers support.
