Hi Rob,
could it be the driver you're using doesn't run with XP??

When I swapped my win98 laptop ( with serial port) for my Dell Xp which only had USB, I had to get a serial/USb interface.
I also switched to a Yamaha driver.

Can't remember if it was wholly & soley to do with USB or may have also been that the original driver I had for win98 didn't support XP.

I don't use the setup anymore as I mainly play my PA800 nowadays. My memory is a bit rusty on how it all came about.

best wishes
Rikki
