Zubax USB I/O on Ubuntu 16.04

What serial or USB port is used for I/O when the Zubax GNSS is plugged into a USB 2.0 port on a PC running Ubuntu 16.04? The GNSS shows up in the lsusb list okay but I cannot determine which /dev/ttt* device can be used for serial I/O.

Many thanks,


Zubax GNSS uses the standard USB CDC ACM class, so it shows up under /dev/ttyACM0 (where the digits at the end can be different). You can find out which exact device to use in two ways:

  1. Look at the output of dmesg after connecting the device to your computer.
  2. By directly accessing the symlinks under /dev/serial/by-id/*. This is the recommended approach. Also see https://kb.zubax.com/x/N4Ah

Great - thank you. Working fine now. :wink:
