Do you unplug the microphone at the end of a song? Audacity only checks for USB microphones when it starts. Plug the microphone in, wait a second and then start Audacity.

Audacity > Edit > Preferences > Devices > Recording.
Select your USB microphone.

What is the make and model number of the USB device you are recording with?

What happens if instead of rebooting, you launch Audacity then choose Transport > Rescan Audio Devices? Can you then choose your USB device from the list of input devices in Device Toolbar ?
