That's the default config provided by the installer.

So PS/2 on /dev/psaux worked once. Then it would be a kernel problem or so.

But you said earlier that pluging on PS/2 did not generate any character
in "cat /dev/psaux" or "cat /dev/input/mice". This needs to be
clarified. Either /dev/psaux works (and generates characters) or it
doesn't at all.

I don't think so.

Please check your BIOS in case there some config for the PS/2 port. And
check whether PS/2 works in other Linux/OS if you can.
