Hi Munken, do you have the latest drivers installed. If not here is a link that has Win 8.1 drivers for the V-Studio 20:

According to this Roland site the V-studio 20 has limited compatibility with Win 8.1:

Another site said the unit will have problems with some USB 3 ports and suggests you only use USB 2 ports.

It sounds like you should dump this and get a better audio interface.
