Thanks for the work. I'm going to give it a try right now!

Hi Bob/coldsource! Smile

I'm using the next Ubuntu distribution:
Distributor ID: Ubuntu
Description: Ubuntu 10.04.1 LTS - XBMCLive Dharma
Release: 10.04
Codename: lucid

I compiled the code successfully now (after deleting the three keys from keys_definition.cpp). After that - I had the same problem as Cucurbitace, I needed to use the beta version. Everything worked, I created a map file, only to test, with this content:
00033002000104280004012000030000:KEY_F

I tried to load this map, but I received this error:
Loaded map file test.map
Found HID device
Opened HID interface on /dev/hidraw0
Unable to setup event device

I have to admit, I skipped a step: to blacklist the device in Xorg, becasuse I thought it's not necessary with this distro.

Could be this the problem?

Should I make a try?

Thx
Diego

Diego,

Could you confirm me that learn mode is working ?
Also check that you are runing hid_mapper as root, uinput won't be able to create device as non-root.

You can also check the properties on uinput file :

Quote:ls -l /dev/uinput

It is possible that your kernel doesn't have built-in uinput support, as root try

Quote:modprobe uinput

And then relaunch hid_mapper.

If none of these work, could you post the result of :

Quote:ls -l /dev/uinput
dmesg | tail
uname -a

Concerning Xorg blacklist, I don't think it could cause the error. It is just used to avoid double keys inputs (from Xorg and from the HID mapper).

Hi Coldsource,

sorry for the late reply, I could not get full access to the computer before, it's the media server of the flat and I had to wait for no one to use it. Wink

Anyway, it didn't work. Sad

Here is the result of the command:

./hid_mapper --learn --lookup-id --manufacturer '13ec' --product '0006'

Code:

Found HID device

Unable to open HID device

At first I thought that is might be because I didn't blacklisted the remote from X11. So I did create a 50-remote.conf in /usr/share/X11/xorg.conf.d like you explained at the beginning of this thread. Here it is:

Code:

Section "InputClass"

Identifier "Remote blacklist"

MatchProduct "0006"

Option "Ignore" "on"

EndSection

And it works, my computer doesn't get input from the remote anymore. But the command still gives the same error.

Hi Cucurbitace,

Are you sure you are running hid_mapper as root ? Detection can be done as non-root but not mapping.

Try running it with a sudo it should work.

- Cucurbitace - 2011-01-26 16:43

Yup, my bad, I used the command as a normal user. Blush

Thanks. I'll give a try again as soon as I have full access to the media center.

- Diego2002 - 2011-01-26 22:12

Hi Coldsource/Bob!

Yes, I can confirm, that learn mode is working, because when I press a button, a lot of numbers appear.

I logged in as root also.

Quote:ls -l /dev/uinput

Quote:ls: cannot access /dev/uinput: No such file or directory

Quote:modprobe uinput
Quote:Returns nothing (no output, not errors)

So the next try:

Quote:ls -l /dev/uinput
Quote:crw-r----- 1 root root 10, 223 2011-01-26 20:52 /dev/uinput

Quote:dmesg | tail

I tried to run once more the command, but now the message is different:

Quote:Loaded map file test.map
Found HID device
Opened HID interface on /dev/hidraw0
Generic USB mapper driver setup

At this point the bash signal dissapears, I can press any button, and only Ctrl-C stops whatewer it does...

Hi Diego,

The main problem comes from the fact that uinput if not built in your kernel. After loading the module with:

Quote:modprobe uinput

uinput is loaded correctly since you can see the uinput main device in /dev/uinput as ls shows.
I think the last try was the good one because the last message of :

Quote:Loaded map file test.map
Found HID device
Opened HID interface on /dev/hidraw0
Generic USB mapper driver setup

proved hid_mapper started correctly.

At this point you should be able to press the remote button you mapped as 'KEY_F' and see a 'F' appear in any X application. If it does not work try blacklisting your remote from Xorg because it can cause confilcts to have both Xorg and hid_mapper listen to the same device.

Remember that hid_mapper must be running when you press the remote button for this to work (pressing CTRL C will quit hid_mapper). If it is working you can do the full mapping and start hid_mapper at boot by starting it in /etc/rc.local.

It is working ! Thanks a lot ! I still have to make a clean map file (5 keys are not recognized and I have to figure out how map all the others). But congratulations coldsource, nice piece of coding you've made. Big Grin

- Cucurbitace - 2011-01-27 22:05

I was hoping to use this post to share my map file, but I found another problem:

Every key that use a value above 9 (A to E) is not recognized by the program.

Here is my actual zydacron.map:

Code:

0100000000520000:KEY_UP

0100000000510000:KEY_DOWN

0100000000500000:KEY_LEFT

01000000004F0000:KEY_RIGHT

0100000000280000:KEY_ENTER

0401000000000000:KEY_HOME

0508000000000000:KEY_PAGEUP

0510000000000000:KEY_PAGEDOWN

0504000000000000:KEY_MUTE

0500020000000000:KEY_TAB

01000000001E0000:KEY_1

01000000001F0000:KEY_2

0100000000200000:KEY_3

0100000000210000:KEY_4

0100000000220000:KEY_5

0100000000230000:KEY_6

0100000000240000:KEY_7

0100000000250000:KEY_8

0100000000260000:KEY_9

0100000000270000:KEY_0

0602000000000000:KEY_S

0402000000000000:KEY_F11

0400200000000000:KEY_V

0408000000000000:KEY_F9

0410000000000000:KEY_F8

0420000000000000:KEY_F10

0480000000000000:KEY_F12

So this keys don't work: BACKSPACE, RIGHT, 1 and 2. I've tried to capitalize, but it doesn't change anything.

coldsource, any idea where it can come from ? Frown

Thanks.
