There may be a simpler solution. The systems I've seen with only one ps/2 jack had both the keyboard and the mouse signals wired to the single jack. (Quick test: if it is wired this way it will work with either a keyboard or a mouse.) If that's how yours is set up you can get a Y adapter with one ps/2 plug and two ps/2 jacks, and not need to deal with USB keyboard or mouse support at all.
