[gentoo-user] ir receiver - mceusb
Petric Frank
Hello,
maybe this is not exactly a gentoo problem. Please point me to correct location if i am wrong here.
I've got a MCE-like ir remote together with a USB receiver.
Looks like it is detected by the kernel and a input device was created.
Most of the keys are working. But - for example - the color buttons do not
generate any output.
"ir-keytable" (version 1.10.1) returns:
Couldn't find any node at /sys/class/rc/rc*.
"ir-keytable -d /dev/input/eventxx" gives as output:
Name: PHILIPS MCE USB IR Receiver- Spi
bus: 3, vendor/product: 0471:0613, version: 0x0100
Using for test
ir-keytable -d /dev/input/eventxx -r
i got:
------------------- cut --------------------
scancode 0x700e0 = KEY_LEFTCTRL (0x1d)
...
Enabled protocols: other lirc rc-5 jvc sony nec sanyo mce-kbd rc-6 sharp xmp
------------------- cut --------------------
But there is no definition of the color buttons in the list above.
Tests were done using this command:
ir-keytable -d /dev/input/eventxx -t
Any hints ?
Is it possibe to see the scancodes received by the USB-receiver to validate
that the remote really sends data for the color buttons. What kernel options i have to enable ?
(Also for checking and not barking at the wrong tree due to hardware problems)
Some info about my system:
Kernel 4.9.6 (amd64) custom configured
Distribution: Gentoo

The remote looks like this one:

but its branded as olidata.
The receiver is detected as (syslog):

something if nothing is created under /sys/class/rc/.

Hello Dan,
Which modules create the entries under /sys/class/rc/.
This is the media drivers part of the kernel config:

Do i miss something ?
Or do i need to load other kernel modules by hand ?

everything. I did find your problem though, although I have no idea how
to fix it:
[ 7.185141] hid-generic 0003:0471:0613.0003: input,hiddev0,hidraw2: USB
HID v1.00 Keyboard [PHILIPS MCE USB IR Receiver- Spinel plus] on
usb-0000:04:00.0-2/input0
obviously.) Presumably this is why it is not creating /sys/class/rc/rc0.
I would assume you'd have to block Xorg from seeing it as a keyboard and
maybe write a udev rule to register the device correctly?
On my mythtv frontend my device (an iMon device) registers correctly as
an IR device:
[ 7.000121] input: iMON Remote (15c2:0038) as
/devices/pci0000:00/0000:00:1a.2/usb5/5-1/5-1:1.0/rc/rc0/input6
I did a quick Google for your device and "keyboard" and this thread
looks promising:
http://forum.kodi.tv/showthread.php?tid=133071&pid=1118999#pid1118999
You might be able to get some information there to stop it from
registering itself as a keyboard. This is for Ubuntu or one of its
forks, so you may have to adjust things accordingly.
Sorry I wasn't much help.
