Hello Amol and Denis, This webcam is not handled by gspca (it is VF0230, and not VF0250). I already got a usbsnoop and I may say that it if not UVC compliant too. With the usbsnoop and the register names in the V0230Dev.inf of the ms-win driver, it should be easy to create a new driver, but: - it seems it asks for a firmware which may be copyrighted, - the images are compressed and the encoding is not known... BTW, the linux video stuff is now discussed in the linux-media mailing list (see Cc:). Best regards. -- Ken ar c'hentań | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
