[c-nsp] ASR920 Usb console issues

[Andrew Lagzdin]

I have good luck using “sudo cu -l /dev/tty.usbmodem<foo> -s 9600” from the terminal when connected to the “USB CONSOLE” port (bottom right). We’re using “StarTech.com <http://startech.com/>” adapters to go from USB-C/Thunderbolt to USB console. 
No drivers required. 

Cheers,
Andrew
