No recording with TASCAM MINI STUDIO

I am trying to use a TASCAM mini-studio U-42 with audacity and it won’t record. I’ve enabled the TASCAM as recording and playback on sound control panel, and audacity is recognizing the device, on MME. Any ideas? I’ve tried rebooting computer and no luck.

If you are using Audacity 2.2.0:
open “Help menu > Diagnostics > Audio device info”.
Save the info when it appears.
Attach the saved info file to your reply.
