OSTC 3 USB not recognized on Ubuntu 20.04

Post by Fabrice »

Hi,
I'm trying to connect by OSTC 3 USB to a PC running Ubuntu 20.04 with no success. It used to work perfectly on the same PC, using the same USB cable (which works with other devices) when the PC was running older version of Ubuntu.

This manifest by having the device not recognized _at all_ when plugged in the PC. I have tried to load manually the ftdi_sio module and to configure it with VID 0x0403 and PID 0x6001 with no success. The kernel logs show absolutely nothing when I plug the ostc in, but the ostc itself is recognizing events (e.g. cable being unplugged).

Any advice on how to fix this? Thanks!

Hi,
does your user have the rights in the dialout to /dev/tty/USBXX to access?

If not, here are the instructions

sudo usermod -a -G dialout $USER

[u]For anyone who likes knowing what they're running before they run it:
[/u]
usermod - modify a user account
-a - add the user to supplementary groups
-G - a list of supplementary groups (man page says to use -a only with -G)
dialout - group that controls access to serial ports (and other hardware too)
$USER - Bash variable containing current username (not a builtin, usually automatically set env variable)
