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.
