devices will not work
Mint 13 or Ubuntu 12.04 by default, because administrative usernames are not a member
of the group "dialout" which is necessary to communicate with /dev/tty* devices.
To fix the problem, enter the following command in a terminal and reboot:
sudo usermod -a -G dialout $USER
This fix is described in opencpn documentation
, but it is way down the list of suggestions and is not specifically associated with these common operating systems:

In my case, the USB-353 GPS
receiver were not recognized in OpenCPN 3.0.2 on Linux
Mint 13 Cinnamon (Ubuntu 12.04 derivative) with Linux 3.2.0-23-generic (x86_64) kernel. Both worked perfectly before the operating system upgrade. I did this fix on two systems, and along with the sound fix described in the link below, my system is now fully functional.
