I am trying to connect an scsi interface on a canon dr 5020 to a usb port on my laptop and have been unsuccessful. I purchased the usbxchange off of amazon.com but have found out that it is not compatible with windows XP. What kind of options do you suggest? I am trying to start a business and this is what is delaying me. Woould it be wise to see about going back to windowsME or 2000 so this usbxchange will work?
