Re: TechnoTrend CT2-4500 remote not working
It would be interesting to see what the device is sending. Please can you turn on dynamic debug for ir-kbd-i2c.c: echo "file ir-kbd-i2.c +p" > /sys/kernel/debug/dynamic_debug/control Try the remote again and report what in the kernel messages. Sean I turned on dynamic debug and got the following messages in the kernel log: [ 837.160992] rc rc0: get_key_fusionhdtv: ff ff ff ff [ 837.263927] rc rc0: ir_key_poll [ 837.264528] rc rc0: get_key_fusionhdtv: ff ff ff ff [ 837.367840] rc rc0: ir_key_poll [ 837.368441] rc rc0: get_key_fusionhdtv: ff ff ff ff Pressing a key on the remote did not change the pattern.
