It seems, that it was an hardware failure.

I tracked the USB communication:
Here is the unsuccessful part - the mouse does not work after inserting 
the adapter:
[...]
< ffff8801b2ed6900 582503866 S Co:021:00 s 21 09 0220 0002 000f 15 = 
20ff8100 00000000 00000000 000000
< ffff8801b2ed6900 582503914 C Co:021:00 -32 0
< ffff8801b2ed6840 582503957 C Ii:021:03 -2 0

With a different unified USB adapter it just works like a charm, without 
problems, so no problem is there :-)

Regards,
Flo
