Thanks.
My son found a web site that sells a Keyboard to USB cable that comes with software drivers for the XP. I ordered one and will give it a try.  I don't think the XP software that came with the laptop will set up the USB port for midi.  I looked through all of the software and couldn't find any way to set up a port.  Seems that XP has midi drivers for internal use but not for setting up a port.  Thanks again everyone for your help.
