- Take a look at page 95 of XV-2020 manual

- in USB DESCRIPTOR change to GEN (Generic)

This way you'll be able to use a simple usb cable, and the module will be recognized. Don't install the original driver because it won't work in Windows 7 and probably not in Windows 8. The XV-2020 Editor works well in Windows 7, and Linux.
The Generic driver mode applies to any module or keyboard with this option. It means if you change to a different Operative System, probably the original driver won't work but you can still use your equipment.

Hope it helped
