USB power & touchscreen issues...
I have a hp f1064a power supply running a m9000 in a cubid 3688.
Everything works fine...until I plug in the touch screen..and then the power supply cuts out...
I suspect it's drawing too much power through the USB socket and consequently tripping the PSU protection circuitry.
Would it work if I switched the 5v source that the touchscreen usb cable is drawing from? (ie use the 5v line off the ps2 port) or could I try a serial to USB convertor? would that be any better than using the standard USB port?
