Prior to R4.11 install, my Fender Mustang I amp was detected by Reaper as a ASIO USB input, and now its not being detected.
As a test to see if my connect was bad, I opened Ableton LIVE LE, and the Mustang amp was detected and I was able to record using the amp's USB connection.
Also, Fender uses a 'Fender Universal ASIO' software, which R4.11 detected but doesn't seem to work.
