That works, but the permissions will probably be reset after a
reboot upor reinsertion of the USB serial adapter.
I'm running Linux Mint, which is based on Ubuntu. On my computer
/dev/ttyUSB*, as created, are owned by the 'dialout' group. The
command 'ls -l /dev/ttyUSB0' should show you the owner and group, it
might not be 'dialout' on your system.
Assuming that your user name is 'username' and the group of
/dev/ttyUSB0 is 'dialout' then you can then add your own user to
this group with the command:
sudo adduser username dialout
That way your user account will automatically have permission to use
any serial ports on the system.
