Keyboard stopped working wired but works wireless. [SOLVED]

So I have a Keychron K6 keyboard. As it is 60% it has two fn keys (fn1 and fn2) I had to change fn_mode to 2.
Two days ago everything worked fine but suddenly it stopped working. This keyboard has Bluetooth, so I tried connecting it that way and it worked.
I have looked for it in the forums but haven't found anyone with a similar issue.
For some reason it also registers as an Apple keyboard, I know Keychron makes keyboards that are designed to be apple compatible.
Any tips on how to approach this would be appreciated.

Sounds like a faulty cable/connection. Try another wired keyboard ans see if that works.

I concur.  You might also check your journal and dmesg for clues left in the logs.

I saved the journal before and after connecting via USB.
I can see it clearly recognizes the keyboard but there seems to be an issue with the settings I changed. I will look into it and post an update.

  update

So I removed the hid_apple.conf in modprobe and now it works. When I alter fn_mode in

 /sys/module/hid_apple/parameters/fnmode 

it works but when I alter it in modprobe the wired mode stops working. I'll add an entry in the wiki to warn other users that this may be the case for them too.
for now I will just add the line in modules at my xinitrc.
Thank you for the help
