HID Remotes

Post by kbocek » Sun Jan 20, 2019 7:39 pm

I'm setting up a new front end and have a HID style remote

Code: Select all

# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 04f2:0402 Chicony Electronics Co., Ltd Genius LuxeMate i200 Keyboard
Bus 001 Device 003: ID 05a4:9881 Ortek Technology, Inc. IR receiver [VRC-1100 Vista MCE Remote Control]
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I get output from ir-keytable with the keys already mapped. But I see two devices /dev/input/event10 and /dev/input/event11. I assume one is the mouse interface and the other is the keyboard.

Will Myth work with two devices and accept codes from both? Or do I need to do some other magic?

I see the wiki page
https://www.mythtv.org/wiki/HID_Remotes

But that talks about /dev/rc devices. This receiver does not create /dev/rc entries.

Thanks

It will work with as many input devices you have. I got one with a ps2 remote KB, a usb remote KB, and a usb ir remote. They can all work at the same time.

Plug in your usb receiver. Type ir-k and hit tab key. If you have ir-keytable on your system, it should display the command. If not, then install it. Then just press the enter key to get the info about your receiver. here's one of mine.
wes@mythfe0:~$ ir-keytable
Found /sys/class/rc/rc3/ (/dev/input/event17) with:
Name: Media Center Ed. eHome Infrared Remote Transceiver (0471:0815)
Driver: mceusb, table: rc-rc6-mce
lirc device: /dev/lirc3
Supported protocols: other lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp
Enabled protocols: lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp
bus: 3, vendor/product: 0471:0815, version: 0x0000
Repeat delay = 500 ms, repeat period = 125 ms
..............
As you can see, I've got all the protocols enabled. yours may not. If you use LIRC, then you don't need any protocols enabled as it receives the raw ir data and you have to have an lircd.conf to interpret the signals. I don't use lirc any longer.

Yes, I've been using ir-keytable:

Code: Select all

$ ir-keytable
/sys/class/rc/: No such file or directory
But

Code: Select all

# ir-keytable -d /dev/input/event0
Name: HID 05a4:9881
bus: 3, vendor/product: 05a4:9881, version: 0x0110
And running with -t gives me output.

My issue is using third-party generic remotes with this receiver. And I think it would be good to run this through LIRC but the instructions out there are confusing.

No I do not have mceusb loaded. Again, this is a HID only device. There are no /dev/rc* entries created. Only /dev/input/* is created. ir-keytable will work on the /dev/input entries and will display keypresses. LIRC I think works through it's devinput driver but I'm not sure.

I am abandoning this stupid Ortek. I've tried a bunch of remotes and a bunch of codes. I can't get a generic remote to work with it.

Fortunately I have another sitting around and mceusb recognizes it just fine:

Code: Select all

/dev/lirc0 is there and ir-keytable sees it just fine:

Code: Select all

# ir-keytable

        Driver mceusb, table rc-rc6-mce
        Supported protocols: unknown other lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp

        bus: 3, vendor/product: 1784:0008, version: 0x0101
        Repeat delay = 500 ms, repeat period = 125 ms
I also ordered the Inteset receiver that I linked to earlier. I'll report on that after I get it.

You shouldn't have a problem with that receiver. Looks like the Ortek receiver is either defective or isn't a real ir receiver. If you need the receiver to support all the protocols it's capable of you need to include them in the first line of the rc_keymaps file you use.
As it is above it only supports the rc-6 protocol
wes@mythfe0:~$ cat /etc/rc_keymaps/myremotes|grep table
# table *, type:rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp

Well crap, this receiver doesn't work either. ir_keytable actually segfaults when a key is pressed. Irrecord just times out with no input. Mceusb driver loads just fine and the lirc config is installed but nothing from irw. The LED flashes on keypresses but again, nothing.

I see old complaints regard this device (1784:0008) and now that I think about it I believe I tried working with this receiver years ago with the same results.

I'll get the Inteset receiver tomorrow. Comments on Amazon are positive and mention success with Kodi. So I'm sure it'll be good here.

If you are going to use ir-keytable, you should remove lirc, or at least while trying to use ir-keytable, make sure you stop lircd from running. I completely removed lirc from all my machines. To ir-keytable to work with my remote, I had to add this line to /etc/rc_maps.cfg pointing to my remotes key map.
wes@mythfe0:~$ cat /etc/rc_maps.cfg|grep myremotes
mceusb * /etc/rc_keymaps/myremotes
And this in that file, enabling all supported protocols on first line.

So I did as you say. I stopped lircd, created /etc/rc_keymaps/myremotes and hurrah! I got clear output from ir-keytable. However, after a handful of key presses the *host* crashed and required a hard boot. I repeated the test. Same thing. ir-keytable would display a bunch of key presses and then the system would hang.

I think this receiver is broken in some way.

BTW, I see you like the RCA RCRP05B remote. My favorite too. Unfortunately the version I have all over the house isn't being made any more. Fortunately I bought some backups. I just did my testing with a RCRN05BHZ which I think is it's replacement. The 4-device version seems to work too.

So you don't use LIRC? My problem is I have some applications that use IRExec to do stuff outside of MythTV. Don't I need LIRC for that?

ir-keytable is the same as a KB input, so you don't need a translation table like you do with lircrc for each app. So if your apps will work with a Kb, they'll work with the ir-keytable, and I'm pretty sure all of them will work with a KB.

I spoke too soon. I got the new receiver and it's working with ir-keytable:

Code: Select all

~# ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event7) with:
        Driver mceusb, table rc-rc6-mce
        Supported protocols: unknown other lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp
        Enabled protocols: lirc rc-6
        Name: Media Center Ed. eHome Infrared
        bus: 3, vendor/product: 1934:5168, version: 0x0001
        Repeat delay = 500 ms, repeat period = 125 ms
What I realized was I was pressing the power button which comes across as KEY_SLEEP and I was putting the host to sleep. A bit of googling and:

Code: Select all

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
systemctl restart systemd-logind.service 
And now ir-keytable displays KEY_SLEEP without the system shutting down.

Oddly, all the keys display except for the volume keys and mute. Maybe I should try a different remote code.

Update: duh, it's what RCA calls "Volume Punch Through". The volume keys are sending for the TV or Audio. No way to disable it. But I don't need the volume keys anyway.

I'm still not getting anything with LIRC and IRW though. I've tried both the MCEUSB and DevInput config files. Nothing. IRRecord does work but I don't really want to have to go through mapping every key.

Update2:
I used the quickie conf file I generated with with IRRecord but with only two keys. Those keys show up in IRW. So the keys defined in lircd.conf.mceusb do *not* match the codes being sent by the remote. I see a whole bunch of remotes using the same key programming code for the RCA. I've just gotta match one of those to the LIRC conf.

Update3:
I shoulda listened to you wesnewell, The answer was Lirc's DevInput conf file. Which is installed by default. With that and the device code on the remote that is used by many devices, I am getting output now from IRW including the color buttons. Yay, this will let me use irexec!
