You can't (normally) plug a PS2 mouse in to a keyboard port and vice-versa, so that won't help to test which is faulty. I meant swapping the cables inside from the ps2 headers to the motherboard, then connecting them in reverse... just to check from the ps2 connector to the MB header. Ive given up …
