Could the problem lie with the ivtv driver? I use neither ivtv nor lirc, so I don't really know who does what, and I can't test either. What if you remove MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT from set_use_inc and set_use_dec respectively? That's almost the only idea I have right now, and I don't really have time to work on it. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
