Hello bigrip, welcome to the forum!
Can you run ls -al commands in your /dev/input and /dev/input/by-id folders, and then copy the result here? I don't need the actual files (and they are virtual files so you could not copy them anyways), I just need to see the names of the files. This might give me ideas as to why rpix86 does not handle the files correctly.
Also, have you tried to start rpix86 with -k0, -k1 or -k2 parameter, to see if one of those would make rpix86 to recognise the keyboard?
Thanks for your interest in rpix86!
