No, I'm afraid it still doesn't work. Now I get only the "Release <Pointer(IConnectionPointContainer)>" line however:

During the PumpEvents phase I moved the device, and it should have registered a lot of events. But nothing happened.

This is with version 0.5.2 now. I did delete the gen folder when changing the version. But I didn't use the output from the first run here, because it was just way too long.
