 Depending on your distribution, you might need to add permission to your user so it can access ''/dev/ttyACM*'' or whatever.

-If you plan to use a USBtiny on Linux to program your Arduino instead of the more conventional approaches, you are likely to encounter a different permission error. On my Debian sid system, I encountered a “Warning: cannot open USB device: Permission denied” error. Adding my user to the ''dialout'' group didn't fix this issue. +If you plan to use a USBtiny to program your Arduino instead of the more conventional approaches, you are likely to encounter a different permission error.
