Back space and windows key are not working

[avifo]

The keyboard was working perfectly fine, but now the backspace key is not working properly and is instead outputting "#" while the windows key is not outputting any data. Initially, I thought it was the EEPROM and as I had that issue before but after I tried the fix in #15 but it did not fix any issue.

Any idea what the cause might be.
