Summerall,
Unfortunatley, you need both the USB and VGA connections for the touchscreen.
Yeah I kinda guessed that would be the case, someday we might get USB everything -- Here's to hoping.
I've ran into problems extending the breakout cable
True, as BaddaBing mentioned the standard VGA extension cables are not shielded so you get ghosting and outside interferance, the dearer cables have shielding around each signal wire which minimises these issues. I have one cable 20 meters in length and a good picture to boot.
