I did some more testing with different kernels and other
constellations and could produce some more variations, in which way
exactly it didn't work ;-) Eventually it turned out that somehow the
cinergyT2 behaves differently depending on which port exactly it is
connected to. I have 8 USB-2.0 ports using 4 different IRQs, some of
them shared with other drivers/devices - maybe that's the real issue.
(even though there never was any log message indicating a problem).
Obviously, if there ever has been a problem, the driver will stay in
an inconsistent state and only recover when it is reloaded.
Anyway - right now it seems to work even with both devices running
BTW, has anybody of you fellow cinergyT2 users ever experienced
crashes killing the keyboard?
I used to have that problem pretty regularly. Right now, I turned off
the /dev/input support, which seems to help, but I am not sure whether
this really is the problem, and could imagine occasions, where the
remote control might be a nice thing to have ...
