Windows 10: WASAPI can't see audio input of generic USB audio device

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?

Windows 10 BSODs

Yes, twice. Both as Headphones (USB Audio Device) and Headset Microphone (USB Audio Device) in Audio Inputs and Outputs which is using the generic Microsoft driver (10/29/2015 and version 10.0.10586.0)

As well as USB Audio Device in Sound, video and game controllers which is using the following drivers:

• dmk.sys
• ksthunk.sys
• portcls.sys
• USBAUDIO.sys
• SysFixUI.dll
• WMALFXGFXDSP.dll

 

Xbox recording has no sound while playedback.

There is something you can try, though it is unnecessarily complicated:

• Use a different screen recorder
• Download Audacity (it's free). Set the audio provider as Windows WASAPI and the input device as your speakers. Then record, and piece the recording together to match the sound.
