Input setting doesn't show USB recording device

Setting preference for my USB cassette to MP3 capture converter, the only device the dropdown menu allows is the built-in microphone. My System Preferences shows USB Audio Device (although the device doesn’t show up in my Finder.
I’m using MAC OS 10.13.2 … Any idea how to get it to register? Thanks!

Make sure the player is plugged in and restart Audacity. Audacity checks for connections when it starts. If you plug something in later, it may not see it. You can also Transport > Rescan.


That works! Thank you!
