hi, my brand new Gigabyte U8000-RG USB tv oops kernel.

I have tried kernels from 2.6.27 to 2.6.31 everytime with same result (also at 
my notebook).

uname -a:
Linux vertigo 2.6.31-gentoo #2 SMP PREEMPT Mon Sep 14 20:20:59 CEST 2009 i686 
Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz GenuineIntel GNU/Linux

lsusb:
Bus 001 Device 005: ID 1044:7002 Chu Yuen Enterprise Co., Ltd

This output is from 2.6.31 kernel and last mercurial snapshot of linuxtv tree. 
Error occure when I try to scan channels in Kaffeine.

dmesg:
