My IFP's USB touch function does not work on my PC but works on my laptop?
The USB port may not be outputting enough voltage to drive the touch feature. Power on notebook PC's USB port seems inconsistent across brands. You have a couple of options: 1) try a shorter cable. 2) Try a different port, better still try a USB 3.0 port if there is one on your notebook. USB 3.0 has more drive power than prior versions. USB 3.0 ports have blue alignment tab. 3) Try a powered USB hub or amplified extender cable
