Support for a USB-connected device

I cannot get Audacity to support a USB-connected cassette capture device. I have tried multiple different devices.
Edit/Preferences – does not have a choice for a USB device as the Recording device. The only choices are:

・ Microphone
・ Microsoft Sound Mapper
・ Stereo Mix

All hardware vendors provide Audacity as the software to use. None of them can tell me why the software does not work.
What is the answer?

Audacity looks for new devices when it starts. Restart and see if it shows up.

Audacity can’t do anything unless Windows gets there first. Does Windows see it?
