[mythtv-users] Mceusb how to transmit IR codes

[Doug Scoular (dscoular)]

Hi All,
                I’m happily running mythbuntu 16.04.2 and have had lircd working with devinput to receive my MCE IR remote control input quite happily.

lsusb shows the device as:

Bus 002 Device 002: ID 0471:060c Philips (or NXP) Consumer Infrared Transceiver (HP)

                For ages I’ve been wanting to play with the transmit side of the mceusb device but all my attempts to use irsend(1) fail with:

root at spug:~# irsend -d /dev/lircd  SET_TRANSMITTERS 0
irsend: command failed: SET_TRANSMITTERS 0
irsend: hardware does not support sending
root at spug:~# irsend -d /dev/lircd  SET_TRANSMITTERS 1
irsend: command failed: SET_TRANSMITTERS 1
irsend: hardware does not support sending
root at spug:~# irsend -d /dev/lircd  SET_TRANSMITTERS 2
irsend: command failed: SET_TRANSMITTERS 2
irsend: hardware does not support sending
root at spug:~# irsend SEND_ONCE "devinput" "MENU"
irsend: command failed: SEND_ONCE devinput MENU
irsend: hardware does not support sending

I can see that various lircd and mceusb kernel modules are loaded but I’m at a bit of a loss as to how to get IR transmission working:

root at spug:~# lsmod|egrep '(lirc|mce)'
ir_lirc_codec          16384  0
lirc_dev               20480  1 ir_lirc_codec
ir_mce_kbd_decoder     16384  0
rc_rc6_mce             16384  0
mceusb                 28672  0
rc_core                28672  14 ir_sharp_decoder,ir_xmp_decoder,lirc_dev,ir_lirc_codec,ir_rc5_decoder,ir_nec_decoder,ir_sony_decoder,mceusb,ir_mce_kbd_decoder,ir_jvc_decoder,ir_rc6_decoder,ir_sanyo_decoder,rc_rc6_mce

The kernel does recognise the device and notices when the IR transmitter is plugged in:

root at spug:~# dmesg|grep mce
[    0.016824] mce: CPU supports 6 MCE banks
[   13.332036] Registered IR keymap rc-rc6-mce
[   13.338220] input: MCE IR Keyboard/Mouse (mceusb) as /devices/virtual/input/input11
[   13.343049] rc rc0: lirc_dev: driver ir-lirc-codec (mceusb) registered at minor = 0
[   13.548043] mceusb 2-2:1.0: Registered   BB+ Dongle(e.d) with mce emulator interface version 1
[   13.548047] mceusb 2-2:1.0: 2 tx ports (0x1 cabled) and 2 rx sensors (0x1 active)
[   13.548084] usbcore: registered new interface driver mceusb

I have read that the devinput lircd driver doesn’t support transmission but I can’t seem to find the appropriate one to use for the mceusb device:

root at spug:~# lircd --driver=help
Driver `help' not supported.

        uirt2_raw

        usbx

Ideally, I’d like to learn how to manually run the appropriate lircd command from the command-line, specify all the needed options and get it working with irsend independent of the mythbuntu startup scripts.

Any help or advice hugely appreciated!

Cheers,

Doug
