Ok, I just submitted the patch to linux-media. You might want to retest
it though, maybe I did some silly mistake...

Regarding the messages, can you turn on debugging in vp702x (modprobing
it with module param debug 3 ) after applying this patch?

It will show where the device is not responding. I guess it's a problem
in the protocol implementation, which is hard to fix without hw-specs.
But let's see what that debugging turns up.

Regards,
Flo

Final patch from Florian + debug patch for diagnosing annoying:
vp702x: usb in operation failed. (-110)
error messages.

Maybe you could find some time for building an other test kernel for me ...

Thank you,
Markus Stephan
