RPI2 ir-keytable not supporting NEC protocol on rc-it913x-v1 #781

Closed nikto-es closed 5 years ago

nikto-es commented 8 years ago

I'm trying to use my IT913x-based USB DVB-T tuner IR remote.

Problem comes when ir-keytable fails to enable its protocol, NEC:

ir-keytable 
Found /sys/class/rc/rc0/ (/dev/input/event0) with:
    Driver dvb_usb_af9035, table rc-it913x-v1
    Supported protocols: NEC 
    Enabled protocols: 
    Name: ITE 9135 Generic
    bus: 3, vendor/product: 048d:9135, version: 0x0200
    Repeat delay = 500 ms, repeat period = 125 ms
ir-keytable -p NEC -d /dev/input/event0 
/sys/class/rc/rc0//protocols: Invalid argument
Couldn't change the IR protocols

Lower-case fails as well.

ir-keytable -p nec -d /dev/input/event0 
Invalid protocols selected
Couldn't change the IR protocols

Any idea what's going on?

Needless to say, irw shows nothing.

ir-keytable does show debug activity:

# ir-keytable -d /dev/input/event0 -t -v

@nikto-es

does

modprobe ir-nec-decoder; modprobe ir-rc6-decoder

make any difference ?
