afaict it looks exactly like the one i'm using.

I have at least four different types of medion remotes, each with a different
layout and features; they all work w/ the same receiver so selecting based on
usb ids won't work. I don't remember if the keymaps were incompatible though.
In any case, i'm assuming the ati remote will work w/ a medion receiver and v/v...
A per-channel module parameter is probably required.

well, the key code changes could be used to distinguish autorepeat from a
repeated keypress, but i found the autorepeat rate to be high enough
(for a remote) and just ignore them, as above.
