As regards renaming usbkbd.c, @Austin there are some reasons why you would
not read the Kconfig. As a beginner, I didn't even configure this part or
read the help text as I used the configuration that comes with Fedora, I
don't know if that's a valid excuse or not though. I'll leave you guys
decide, you're the experts!

As regards the issue with my capslock led I'm still looking into it.
