Yes, i know. The command to power on the camera is exactly that one i wrote in the example in the previous message. The problem still remains. Infact vendor documentation says: "Before configured, the W9968CF should be reset (CR00_4 = 0) [...] After configured PWRDWN and PWRDWN# pins should be inactive by programming the Camera Power-on Control register to one (CR00_4 = 1) to enable device functions [...]" > For an example of control pipe use, see the sourceforge > project linux-usb/usbvideo (webcamgo.c) Where is it exactly? i didn't find the project. It exists a very pre-alpha version of a driver for those webcams, but it is unuseful, incomplete, old and above all it doesn't work. I read the whole USB/linux documentation about control pipe use and i saw a lot of examples about it. I also tried to copy some sniffed register values from the windows driver. The first command it gives to the camera is "Power-on", which uses the same values i specified in the example.
