just tried that but still no video0 device.
here my lsusb output:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
i think the stk1160 module is missing which was in earlier version included in the hauppage driver add-on.
a modinfo usbtv just give me Fushicai USBTV007:
