You don’t need to install a device driver on your computer or other device to do this (the SP-404MK2 supports USB Audio Device
Class 2.0 specs).

●
Note that data cannot be directly transmitted/received between the SP-404MK2 and your computer or mobile device if
you’re connecting through a USB hub.
