I have a very old Roland audio interface (UA1-EX) which I have to use in its generic USB audio mode because it is no longer supported by Roland. I have been able to get it working using ASIO4ALL and record from its audio input, albeit very poorly. So I decided to try using it with WASAPI. However in my DAW's audio device controls, the mic input of the interface is not listed, even though its ouput is. Why would the input of a generic USB audio device not be available in WASAPI?
