----- Original Message ----- > Hmm... that's weird. Are you sure about that ? Is this really a 3.9.2 vanilla kernel ? Quite sure, although it turns out that there's a bit more to it. Here is the dmesg output with my debugging messages in: [ 6263.496794] em28174 #0: Calling em28xx_ir_change_protocol... [ 6263.533332] em28174 #0: Calling em2874_ir_change_protocol...(type=1) [ 6263.576099] Registered IR keymap rc-pinnacle-pctv-hd [ 6263.607181] input: em28xx IR (em28174 #0) as /devices/pci0000:00/0000:00:1d.7/usb10/10-4/rc/rc6/input22 [ 6263.608329] ir-keytable[30882]: segfault at 0 ip 0000000000401cc0 sp 00007fff7ca22dd0 error 4 in ir-keytable[400000+8000] [ 6263.756019] rc6: em28xx IR (em28174 #0) as /devices/pci0000:00/0000:00:1d.7/usb10/10-4/rc/rc6 [ 6263.816551] em28174 #0: Calling em28xx_ir_change_protocol...

But then I need to call ir-keytable: # ir-keytable -a /etc/rc_maps.cfg -s rc6 [ 6284.491992] em28174 #0: Calling em28xx_ir_change_protocol... [ 6284.528492] em28174 #0: Calling em2874_ir_change_protocol...(type=1) And this seems to reset the protocol back to "unknown". (But I need to use this other remote control to use VDR - the PCTV one just doesn't have enough buttons).
