I hope this is the correct place to ask this question. Please keep
reading (I understand that you have rolled your eyes as soon as you saw
the 'backspace' word).
Long story short, the kernel is not passing on backspace information to
the system. Kernel is 4.10.8-200.fc25.x86_64.
During normal running operation after my disk filled up and fedora
failed to upgrade backspace stopped working. However, I can't tell for
certain it was because disk space filled up. It just suddenly happened.
xev, showkeys and evtest do not show any key code for backspace.
journalctl does not show unknown key message and I used wireshark to
prove that usb does send keycode showing this is not a hardware problem.
So, when I press backspace 0x81 usb endpoint sends 0x2a to the kernel or
whoever receives these messages from the usb device (my point is that
the code gets into the software from the usb device). From this point
onward nothing seems to happen to this code. My question is, what should
my steps be in order to diagnose what's happening with the key inside
