Ok so i am a little new at this and I've looked for the better part of 2 days to see if I could find any similar cases but haven't at least as of yet.. so I have a 2.4 mcufriend tft lcd shield running on a UNO board, have loaded the touch calibration sketch and it loads fine, when the prompt shows touch to continue, touch as I might it won't give any feedback, zero ( usb is still plugged into cpu) but... when i unplug it from the usb port and plug in the external power source, calibration works just fine.. plug back into the pc and it's back to no reeponse.  Any light on the subject is appreciated ten fold!

**UPDATE**
Still having the same issue and can't figure it out at all, any thoughts or ideas of which direction to go would help a lot

Which display?
Which library?
Which example sketch?

There is an updated version of the Touch Calibration sketch attached to this message
