stv06xx devices have only one altsetting, but the actual used bandwidth can be programmed through a register. We were already setting this register lower then the max packetsize of the altsetting indicates. This patch makes the gspca-stv06xx update the usb descriptor for the alt setting to reflect the actual packetsize in use, so that the usb subsystem uses the correct information for scheduling usb transfers. This patch also tries to fallback to lower speeds in case a ENOSPC error is received when submitting urbs, but currently this is only supported with stv06xx cams with the pb0100 sensor, as this is the only one for which we know how to change the framerate.
