I still did not get the keyboard to work but recently I purchased two gamepad and those work well.

from IRC I got the hint that MAYBE this might have something to do with the installation method. So instead of installing the binary packages, I ran retropie-setup doing a source install yesterday. This did not change the behavior.

Also changing the input driver to sdl2 makes the error message about udev not finding an input device go away but keypresses are still not recognized.

so I ran strace on retroarch and it seems that some links of udev are wrong or missing. The strace can be founde here: http://dl.ffm.freifunk.net/pastebin/aikohdohjo

I am running retroarch as user pi (the user is in the input-group) like this:
/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-gambatte/gambatte_libretro.so game.smc

just a me too. – I am experiencing the same problems. From readin the log of retroarch this is not surprising.

I do have a USB-keyboard attached and it is working fine – I can type in the console. So I checked the permissions as suggested in the error-message.

originally the event-devices had 660 set, I tried setting o+rw as you can see but the error message did not change.

Where should I go from here?
