Sorry I thought you meant the Roland had USB.
Here's a Win 7 Generic USB Midi Driver I have used that for the older USB Midi Devices.

EDIT: I remember now you just Extract the folder, go to Device manager find the USB Midi Interface, right click update driver and point it to the Driver folder\emuxmidi.inf
