user permissions

Asked by Laurence Kramer on 2017-03-18

I have to run gtkterm under sudo to use it at all. I get "Cannot open /dev/ttyUSB0: Permission denied" when using it without sudo. Also when I'm in the program and try to change a setting in the configuration like adjusting the baud rate, it accepts the change but when I go back into changing it, it's like I never did. it will only work if the device is connected and I have CTS & DSR indications.

I'm using Linux Mint 17.1 64bit. connected to a Prolific PL2303 USB to Serial adapter connected to an HP 1910-8G Switch (JG348A)

Linux Mint isn't supported here or in any of the Ubuntu support channels. Mint has its own forums and community which is completely separate from Ubuntu.
