Hi all,

I have an Chinese made generic remote USB/Bluetooth, the OK / Select button doesn’t work. I’m trying to remap the button. I have the hwdb file created with the help from this post the only thing i’m not sure about is what to name the file. Could something help me.

below is the info from the device.

Hi, thanks for the suggestion, have tried this before, when I edit the key, it shows a number 16839168, I save the configuration, but it still doesn’t work.

From the evtest, i’m getting the following from the OK/Select button
Event: time 1575931921.867946, type 4 (EV_MSC), code 4 (MSC_SCAN), value c0041
Event: time 1575931921.867946, type 1 (EV_KEY), code 353 (KEY_SELECT), value 1
Event: time 1575931921.867946, -------------- SYN_REPORT ------------
Event: time 1575931922.059918, type 4 (EV_MSC), code 4 (MSC_SCAN), value c0041
Event: time 1575931922.059918, type 1 (EV_KEY), code 353 (KEY_SELECT), value 0
Event: time 1575931922.059918, -------------- SYN_REPORT ------------

On my hwdb file, i have the following entered.
evdev:input:b0003v7545p2804*
KEYBOARD_KEY_c0041=enter

when i run the commands
CoreELEC:~ # udevadm hwdb --update - i get the following statement
/storage/.config/hwdb.d/99-x20IC.hwdb:2: Property expected, ignoring record with no properties
same for
CoreELEC:~ # systemd-hwdb update
/storage/.config/hwdb.d/99-x20IC.hwdb:2: Property expected, ignoring record with no properties
and then i run this
CoreELEC:~ # udevadm trigger

I think my problems is with the name of the .hwdb file, i’m not sure what it needs to be named. Any suggestions?

thanks
Paul

You are missing space in front of second line (before KEYBOARD_KEY_…). Content of the file must be

evdev:input:b0003v7545p2804*
 KEYBOARD_KEY_c0041=enter

Hi Liffey,

Glad you got it worked out. Can i ask you, what did you end up calling the file, and where did you place it?

Thanks
