OK, then /dev/ttyUSB0 is your device (capitalisation is important).

Please do

sudo chmod a+rw /dev/ttyUSB0

after connecting the cable and the D4. If that solves the problem, then it is really the permissions problem that we are all trying to address. But it might be something else. Unfortunatly, this solution is only good until the next reboot (or possibly disconnect of the cable, I am not sure).
