Good, that's how it should be. > But that still doesn't seem to stop ir->rc_type being RC_BIT_UNKNOWN in em2874_polling_getkey(). Hmm... that's weird. Are you sure about that ? Is this really a 3.9.2 vanilla kernel ? The code looks good, ir->rc_type is updated by em2874_ir_change_protocol() when the protocol is changed. I also tried to reproduce your problem with a em2884 device with a RC5 remote control a few minutes ago, but everything works as expected... One thing I noticed is that in em28xx_ir_handle_key() ir->last_readcount is reset to 0 for the em2874 and em2884. I assume the same should be done for em28174, too... Anyway, that's a separate issue and older kernels did the same.
