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.
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:
- Look at the output of
dmesg after connecting the device to your computer.
- By directly accessing the symlinks under
/dev/serial/by-id/*. This is the recommended approach. Also see Using USB devices with GNU/Linux - Knowledge Base - Zubax Knowledge Base
Great - thank you. Working fine now.
