I found that it’s possible to unload and reload the driver with modprobe -r em28xx and modprobe en28xx, need to get the device released first, probably need to stop MythTV or maybe it’s possible to get it to release some other way.

I also found that since I upgraded to Ubuntu 14.04.2 (for the 3.16 kernel for the T292) my T290 & T292 are now working for most of a month (or however long since 14.0.4.2 was released) without needing a driver reload or replugging. Before the T290 needed a replug or driver reload anything from a few hours to a week!

You can’t buy the T290 any more, even if you think you are buying a T290 they will send you a T292 instead, several friends have been caught out! Since the 3.16 kernel the T292 seems to work fine though.

I think there is some issue with the T2 switching in MythTV but I’m not using mine in MythTV yet, still testing. I’m using mine only on the HD mux (only the main one here) as I’m only interested in the HD channels.
