I only added the -S parameter for every of my miners: -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3 (right after the call for cgminer after the screen command, could post the exact content later if needed)
That seems way to complicated for everyone to do

I bet you 1 bitcent that the cgminer guys have got it cracked, grab a new image from here;-
