No, nothing found at all.

Unplugged the 292e, and plugged one of the old SD tuners in (same USB 
port and same aerial cable), deleted all tuners from MythTV again, added 
the new one and the scan worked fine.

MythTV can see the tuner, but a scan produces nothing.

It works find on Windows, but not on my MythTV backend system.
