Hi,
I have a fairly old dvico dual digital 4 tuner and remote.
There seem to be some issues with support for it, can I help fix them?
I am using ir-keytable 1.10.0-1 on Ubuntu 16.04 LTS,
with kernel 4.4.0-47-generic (package version 4.4.0-47-generic)
The remote's keymapping is the one in /lib/udev/rc_keymaps/dvico_mce;
kernel support for the device is in media/usb/dvb-usb/cxusb.c.
Mostly it works, in that I get correct keycodes back from evtest
and ir-keytable -t. But I want to change some of the keycode mappings
and that is not working.
# cat >testfile
0xfe47 KEY_PAUSE
^D
# ir-keytable -v -d /dev/input/event15 -w testfile
Parsing testfile keycode file
parsing 0xfe47=KEY_PAUSE: value=119
Opening /dev/input/event15
Input Protocol version: 0x00010001
fe47=0077
Wrote 1 keycode(s) to driver
So far so good, yes? But evtest still reports the same keycode
for the key I tried to modify.
# evtest
<select device 15>
<press PLAYPAUSE key on remote>
Event: time 1479206112.262746, type 1 (EV_KEY), code 164 (KEY_PLAYPAUSE), value 1

# irkeytable -r -d /dev/input/event15 |grep PAUSE
Enabled protocols: unknown rc-5 sony nec sanyo mce-kbd rc-6 sharp xmp
scancode 0xfe02 = KEY_PAUSE (0x77)
scancode 0xfe47 = KEY_PLAYPAUSE (0xa4)
I thought that I might need to clear and replace the entire table
to get things working. This is where the problems really start.
First trying to clear the table causes an infinite loop.
# ir-keytable -d /dev/input/event15 -c

Then I tried to load a modified version of dvico_mce
The whole file was there, with just this change:

0xfe0d KEY_STOP
The program seems to parse the modified file ok but then
segaults while reading from the input device.

Is this just operator error?
What further diagnostics would help?
