Good to know that lock lights works now.

These two issues are still left at this point.
1) Lock lights are not updated at startup. They won't correspond with lock status of computer after startup.
2) The keyboard doesn't response to 'Read keyboard ID' command(wF2) for some reason.

I updated firmware to test the issues. Can you try this firmware instead of the last? ... usb/binary

Sorry for the delay, my shoulder shat itself yesterday and I basically couldn't move my right side, but I'm fine now, with the new firmware the keyboard doesn't put characters on the screen anymore and the lock lights don't work either,

here the debug output, I pressed f2 at the end;

Waiting for new device:...

Thanks for your patience. And take care of your shoulder.

Firmware you tried(TMK:f8ce50eb/LUFA) is old version from Feb 9 for some reason, not the latest one.

Could you try download firmware file from here and test again? ... usb/binary

The firmware should show version string `TMK:3163a11a/LUFA` in debug log.

No rush at all, try this when you have spare time.
Have a great weekend!

also in hid_listen it says it's xt

Thanks for reply.
Is that all you got in hid_listen?
Debug output during the keyobard "works fine" and when "you turn on lock lights" would be helpful.

Can you post debug outputs long as possible here or somewhere like
