I'm going to guess that if you ran something like "ls /dev/ttyUSB0", you
would get information that help you further.
$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Aug 6 23:22 /dev/ttyUSB0
that would indicate that you either need to be root, or a member of the
dialout group to access that device.
So you can either add yourself to the dialout group, or run the command
with 'sudo' to temporarily elevate your privileges while you use it.
