I was following the answer to this question, as I myself was having a similar issue with my Gamdias keyboard. Unfortunately, not only did it not work, now the entire keyboard doesn't work (not even the NUM LOCK key light changes, the keys light up though).
What could I do to undo any changes done?
I am running 14.04.

? If the number is different it may still work with the same drivers but step 2 has to be changed accordingly. Please check, runlsusb
