Jupiter SDR connection via USB C

I have a Jupiter, and I want to connect as in "Use Case 1 - data streaming to a host computer".  But I can't use ethernet.  So I have the micro USB connected, as well as USB C data and a separate USBC for power. I have the Pluto USB drivers installed.  I see the micro USB UART (COMx), and can connect to it via Putty.  But the only context it gives me is "local:"

I also cannot connect to this, even using the COMx port, in IIO scope or Scopy.  Is there something I'm doing wrong?  Thanks!
