The only other common issue I know of is manufacturers adding a new usb id for the same device which then needs to be added to the driver but I think I can see in your logs that your T292e has the same USB id as my T292e.

Time to talk to Antti Palosaari on the linux-media mailing list or his blog unless anyone else has suggestions?
