FS#13698 - Rockblox don't accept control commands
FiiO M3K - you have to hold up or down before the pieces will rotate
AFAICT the scrollpad on the m3k is being presented as a scrollwheel
and it waits for 3 events before enabling rotation.
This behavior is blocking the user presses till you get a repeat event
Fix:
Enable the scrollwheel at start for the m3k (and m3k linux)
