As far as I know, libusb cannot do isochronous transfers yet (which are used by a lot of webcams). What kind of protocol does your camera use? Apparently, some of the newer (and expensive) ones use the USB video class standard. CRC error does not make sense to me in response to a usb_set_configuration call. What argument do you use? It is in line with the device descriptor?
