[SOLVED] can't open device "/dev/ttyUSB0": Perm. denied (Linux permissions)

Development Tools IDE 1.x

In my case, when I got this message

can't open device "/dev/ttyUSB0": Permission denied

the solution turned out to be to change the permissions on the port:

sudo chmod ugo+w /dev/ttyUSB0

I have not found a way to effect this permanently, and therefore have to do it every time the port is unplugged.
