one way is the shell command 'usermod', but most linux distros provide a
GUI for user mgmt.
by running chmod 777 you made the device file r/w/x accessible by
everybody (including yourself) rather than adding yourself to the group
that had/s permission to access the file (which is what usermod can do
with the -G option).
i suppose that if after chmod you still had problems, then the problem is
not strictly a permission problem.

Do you have write access to /dev/ttyUSB0? (the easiest way to ensure
this is typically to add yourself to the uucp group)
