whenever i have the device plugged into via USB it doesn't respond well to touch based commands. anyone else deal with this??
When plugged in the electrons in your device become super excited, and unable to contain themselves, bounce up under your touchscreen, screaming "Yeah!" (you can hear them if you put your ear real close). This agitation effect of the touchscreen causes temporary inaccuracy and instability.

Funny but you're not that far off. It's due to a combination of fluctuations in line current which translate into variances in the voltages being supplied to the battery, and any lack of proper filtering of that charging voltage by lower quality chargers, coupled with the battery current draw which also fluctuates as it's charging. These variances all confuse the circuitry that monitors capacitance levels of the digitizer surface and fools it into thinking your finger is somewhere it is not or thinking it's moving.

Get your phone away from any RF would be my first suggestion. Curious if you are using the USB cord that came with the phone or some other after market cable. If you plug it into the wall charger, with the same USB cord, does it still happen? And if it still happens are you using the charging adapter that came with the phone?
