I don't know the answer but I suspect the best place to start looking is the Mame Cabinet building scene. Although last time I poked around there there was a heavy bias to installing Windows on those machines.
Does it have to be USB ? I am assuming that some coin selectors have simple switch or digital outputs that it would be trivial to interface to a parallel port ? or you could shove a PIC in the way and do it in serial (in fact you wouldn't even need to code the PIC much if you didn't feel like it as there are probably example projects that do high/low input to serial output) USB adds a bit of complication.
