thanks. would you be in a position to test a fix for this, if i sent
you a new olpc-kbdshim binary to try? i prepared a patch some time
ago for kbdshim, which causes it to (mostly) ignore external devices.
but since i don't have makeymakey hardware, it never really got
tested. i think the same patch may solve your problem.
but first, please try this:
- disable kbdshim, as you have done previously.
- run "sudo evtest". this will show you a list of
system input devices.
- one of those devices should be your logitech device. select
it by number.
- it will dump a list of supported events and properties, then
it will loop, reporting individual events as they arrive from
that device. i'm only interested in the initial list of events
and properties, so you can use ^C to kill evtest as soon as you'd
like.
- send me the resulting output.
