Comment 24 for bug 873247

Im sorry neither kernel 3.1rc9 nor 3.1.daily (3.1.0-999.201110171146) did solve the problem

As I've written I've tried too latest v4l git. So either the problem is in v4l itself - wrong frontend selected - or somewhere else.

As I've googled in the meanwhile i2c errors are serious, and are not related to udev (which was my faulty guess). So - as the usb id's for the device are correct - I believe now that something inside v4l goes wrong. I investigate further to find out the mystery.

BTW. another user is affected see : http://forum.ubuntuusers.de/topic/dvb-t-stick-wird-von-kaffeine-nicht-mehr-erkannt/ (regards, german only)
