[PROBLEM] lirc, mceusb and generic HP USB IR receiver

[dharmabm]

ok, i am at wits end with this... i have tried everything i know (and i am not new to this) and cannot get my remote to work consistently. it works most of the time in rc1, but occasionally does not - either only a few buttons work or it doesn't work at all, usually a reboot or 2 will fix it. but in staging i cannot get it to work at all. i have been through everything in THIS THREAD, as well as dozens of xbmc, openelec and lirc forums and nothing gets a response from irw or mode2.

i am now at the point that i am shopping for a flirc or a gpio receiver, but they are not easy to find in this part of the world, plus i know it CAN work and would like to figure it out as it may help others if we can get to the bottom of it. i suspect a conflict with ir-keytables, but documentation on the relationship between that and lirc is spotty at best. @CurlyMo, can we use this as a scenario to put together a step-by-step troubleshooting procedure that is worth adding to the wiki? after all, it ain't rocket science (or is it?).

[CurlyMo]

Can you unload all rc modules and just load lirc_dev and mceusb. Then restart lirc.

tried everything in that thread already, but thanks. like i said i know how to do this and NOTHING has worked. unfortunately i can't test anything tonight as my file server has died so i have to re-purpose my spare pi so my 6 year old can watch his tv. i have spent hours and days getting this to work in the past, but something new is causing all my previous configurations to fail.

[dharmabm]

fyi, i checked my working rc1 build and irw returns mceusb as input device. i still suspect ir-keytables as the culprit here, but without irw working i cannot verify if devinput is taking over. any ideas?

@dharmabm

you have loaded all kind of protocol handlers, but ... did you set LIRC handler as ACTIVE handler?

ok probably this means yes

Code:

[   24.196843] rc rc0: lirc_dev: driver ir-lirc-codec

disable devinputs, definitely

---

when you have
ir_lirc_codec + lirc_dev + mceusb = you have to go with lircd
rc_rc6_mce + ir_rc6_decoder = you go through kernel input device translated by map defined in /etc/rc_maps.cfg
