RC stop working after upgrade from 7.95.1 to 8

vink78 · February 22, 2017 at 7:56 PM

Hi,

I've a Terratec USB Cinergy HTC Stick which stopped working when I upgraded my install from 7.95.1 to 8.0. I've already read other post related to Remote Control issue, but, I did not find a simple guide to solved my issue:

ir-keytable seems to be OK:

> Found /sys/class/rc/rc0/ (/dev/input/event14) with:
> Driver em28xx, table rc-nec-terratec-cinergy-xs
> Supported protocols: rc-5 nec rc-6
> Enabled protocols: nec
> Name: 1-4: em2884#0 IR
> bus: 3, vendor/product: 0ccd:00b2, version: 0x0001
> Repeat delay = 500 ms, repeat period = 125 ms

evtest seems to be OK too:
> evtest /dev/input/event14
> Input driver version is 1.0.1
> Input device ID: bus 0x3 vendor 0xccd product 0xb2 version 0x1
> Input device name: "1-4: em2884#0 IR"
> Supported events:
> Event type 0 (EV_SYN)
> Event type 1 (EV_KEY)
> Event code 2 (KEY_1)
> Event code 3 (KEY_2)
> Event code 4 (KEY_3)
> ...

But when I press a button, I've no effect on kodi interface.

What are the next steps I should check?

Thanks,

Vink

Hi,

Even ir-keytable seems to work:

<code>
# ir-keytable -t
Testing events. Please, press CTRL-C to abort.
1487877371.650756: event type EV_MSC(0x04): scancode = 0x1402
1487877371.650756: event type EV_KEY(0x01) key_down: KEY_1(0x0001)
1487877371.650756: event type EV_SYN(0x00).
1487877371.754081: event type EV_MSC(0x04): scancode = 0x1402
1487877371.754081: event type EV_SYN(0x00).
1487877371.857443: event type EV_MSC(0x04): scancode = 0x1402
1487877371.857443: event type EV_SYN(0x00).
1487877372.114018: event type EV_KEY(0x01) key_up: KEY_1(0x0001)
1487877372.114018: event type EV_SYN(0x00).
</code>

How can I set libreelec to use ir-keytable?

When I compare dmesg between the two version, one difference is the device name:

-input: em28xx IR (em2884 #0) as /devices/pci0000:00/0000:00:14.0/usb1/1-4/rc/rc0/input18
-rc rc0: em28xx IR (em2884 #0) as /devices/pci0000:00/0000:00:14.0/usb1/1-4/rc/rc0
+input: 1-4: em2884#0 IR as /devices/pci0000:00/0000:00:14.0/usb1/1-4: em2884#0/rc/rc0/input18
+rc rc0: 1-4: em2884#0 IR as /devices/pci0000:00/0000:00:14.0/usb1/1-4: em2884#0/rc/rc0

May blank char create the issue?

Ok. Using comments done by HiassofT on another thread, I've done some progress:

I've download a sample lircd.conf found here: lircd.conf.devinput (I only use the first remote definition).

I've started lircd:
/usr/sbin/lircd -H devinput --device=/dev/input/event14 --output=/run/lirc/lircd-lirc0 --pidfile=/run/lirc/lircd-lirc0.pid --release=_LIRCUP /storage/.config/lircd.conf.devinput

Then, I run this script:
/usr/sbin/lircd-uinput -R 250 -a --release=_LIRCUP /run/lirc/lircd-lirc0

Now, keys seem to work

Next step will be to write an autostart script

Could you please post the output of

Code

udevadm info -a -n /dev/input/event14

First check the exact event number via ir-keytable, it might change, so you'll have to adjust the command above.

Hi,

I've posted the output of udevadm here: GIGX

Thanks! The output looks OK and the remote should have been picked up by eventlircd (or kodi). Very strange, not sure what's going on there.

Could you try the following:

Unplug the Terratec receiver, then power up your libreelec box. When it's up ssh in and run these commands:

Code

systemctl stop kodi
systemctl stop eventlircd
udevadm control -l debug
/usr/sbin/eventlircd -vvv -f --evmap=/etc/eventlircd.d --socket=/run/lirc/lircd

Then plug in your Terratec receiver. After a few seconds eventlircd should have detected the IR receiver and output some info. If it succeeded it should look like this:

Code

eventlircd[801]: /etc/eventlircd.d/default.evmap: using 0 valid keyboard shortcut mappings
eventlircd[801]: input device /dev/input/event3: events of unsupported event type EV_MSC will be discarded
eventlircd[801]: input device /dev/input/event3: event code 0x04 of unsupported event type EV_MSC will be discarded
eventlircd[801]: input device /dev/input/event3: events of unsupported event type EV_REP will be discarded
eventlircd[801]: input device /dev/input/event3: grabbed

Then stop eventlircd with CTRL-C and post the output you got on the terminal and the journal

Code

journalctl -a | paste

so long,

Hias

Ok. maybe libreelec detect the wrong device?

Code

LibreELEC:~ #  /usr/sbin/eventlircd -vvv -f --evmap=/etc/eventlircd.d --socket=/run/lirc/lircd
eventlircd[966]: /etc/eventlircd.d/default.evmap: using 0 valid keyboard shortcut mappings
eventlircd[966]: input device /dev/input/event2: grabbed

This text was displayed before I plug my device. No more text was displayed after I plugged it.

journalctl -> dZDA

Saw in the log that you also had lircd running. Could you repeat the test with lircd/lircd-uinput disabled?

The "/dev/input/event2: grabbed" output is normal, this is eventlircd handling your powerbutton. But in addition to that event14 should be listed there, too after you plugged in the receiver. Could be that lircd grabbed the input device before eventlircd, therefore the need to run the test without lircd in the background.

It was my custom autostart script:

Code

/usr/sbin/lircd -H devinput --device=/dev/input/event14 --output=/run/lirc/lircd
-lirc0 --pidfile=/run/lirc/lircd-lirc0.pid --release=_LIRCUP /storage/.config/li
rcd.conf
/usr/sbin/lircd-uinput -R 250 -a --release=_LIRCUP /run/lirc/lircd-lirc0 &

I've killed these two process before starting eventlircd, and, before plugged in the USB stick:

Code

Mar 28 19:42:54 LibreELEC lircd-0.9.4c[749]: Info: closing '/dev/input/event14'
Mar 28 19:43:36 LibreELEC eventlircd[966]: /etc/eventlircd.d/default.evmap: using 0 valid keyboard shortcut mappings

Ah, sorry, I've missed that before.

Logs and config all look fine: the eventlircd udev rule is processed correctly by udevd (it calls wakeup_enable) but for some reason eventlircd doesn't want to pick up the input device.

I ran an identical test on my RPi with a Hauppauge USB dongle and eventlircd picked up the input device just fine.

Very odd, no idea what's going wrong here - maybe I missed something or maybe there's a bug hiding somewhere.

So until we have a better fix just stick to the lircd devinput workaround, at least this seems to be working fine

so long,

Hias

I've upgraded my install to 8.2.1MR:

- My custom autostart/lircd script is no more need.

Great work. Thank you
