Disklavier

Hello, I received my piano in March and am just now seriously starting
to connect the piano to a computer that sits two feet away.  I've
downloaded Power Tracks demo because I didn't know what else to try
and I haven't opened it yet.
Anyway, I have been reading that I need a cbx driver when using the
"To Host" connection. I have an IBM 500Mhz computer with operating
system windows98SE which is the upgraded version of windows98. The
Yamaha site lists the cbx driver as available for windows 95/98/ME and
doesn't mention 98SE. Does anyone here know for sure if the cbx driver
will work with 98SE? I will call Yamaha when they are open but for now
I'm trying to get this thing up and going this morning. Thanks, Mike

Also does anyone know if it's possbile to connect a cable to the "To
Host" port with a usb hub instead of to a serial port. My serial ports
are already taken and I'd rather not have to disconnect something.
Thanks again, Mike
