Can I do a simple chmod? Or is there a way to run ROS as root? When I run it with sudo it get 'command not found':
No, you don't need to and you should never (well, never ..) do that. See Rosrun as super user.

Under Linux, drivers are always installed as root (directly or via sudo), as that is the only user allowed to do that. The permissions of the device file (in your case /dev/ttyUSB0) can be configured separately.
