Description:
I have a Gigabyte U8000-RH USB tv tuner which worked fine in 2.6.30 kernel. After upgrading to 2.6.31 the card stopped working and I get following output in dmesg.

When I plug the card in:
usb 2-4: new high speed USB device using ehci_hcd and address 5
usb 2-4: configuration #1 chosen from 1 choice
dib0700: loaded with support for 9 different device-types

dvb-usb: Gigabyte U8000-RH successfully initialized and connected.

So far so good, when I start Kaffeine or any other application for watching TV, this error appears:
