Where can I find (64-bit drivers, Windows 7 drivers, etc.) for my US-122?
The final drivers for the US-122 are Windows XP (32/64-bit) or Windows Vista (32-bit) compatible.These drivers are available for download here. If you need drivers for a different operating system, you need to upgrade to one of our currently-manufactured audio interfaces.
