Created attachment 127495 [details] Evemu Log Some keys on my HP multimedia keyboard are not recognized, no reponse when running libinput-debug-events, but they are recognized running evemu-record, attached is a log.
If you only get a MSC_SCAN but no EV_KEY event within the same frame this means the key isn't mapped in the kernel. Please label the various MSC_SCAN codes with what the key is supposed to do, according to the keyboard's key labels
Created attachment 127562 [details] labelled msc scan keys Here are MSC_SCAN keys with labels from keyboard.
sorry about the delay, this fell through. short summary: this would need to go into systemd's hwdb (60-keyboard.hwdb) but I fail to see any identifying information for that keyboard, so I'm not sure we can make a generic match here. Is this a laptop? The dmi only includes the gigabyte motherboard's information and the keyboard claims it's connected via serial bus. either way, the solution to this would be a blurb simliar to others in the 60-keyboard.hwdb file. A match string, together with the scancode to event code mappings. example here: evdev:atkbd:dmi:bvn*:bvr*:bd*:svnHewlett-Packard*:pn*Presario*CQ*:pvr* KEYBOARD_KEY_d8=f21 KEYBOARD_KEY_d9=f21 You'll need to convert the scancodes into hex (e.g. 159 -> 0x9f) and then add the entries. the key names are in /usr/linux/input-event-codes.h, just lowercase it and remove the KEY_ prefix. If we can't find any identifying information, you'll have to keep this as a local override in /etc/udev/hwdb.d/
