I use USB, for a very simple reason:
- When I hook up a mouse as a USB device, it shares an interrupt with
every other USB device connected to the system.
- When I hook up a mouse as a PSAUX device, it requires a hardcoded
interrupt 12 that is then not usable by anything else.
It's less of an issue on my current computer, which uses an APIC
interrupt controller and thus has lots of spare interrupts; but my previous
machine (a K6-2 on a 'super 7' motherboard) was full to the point where I
was having to count interrupts.
There's also the fact that a number of newer computers are coming out
_without_ the old PS/2 mouse port as part of the drive to 'legacy-free'
systems, but that's not really a consideration for what you're doing now,
just something to keep in mind for the future.
