FIXED!!!! i used I_Arduino1.xml and L_Arduino.lua from development branch and now the plugin its working!!!! I'll include some sensors and check if everything works

Unless you plan to move it around, soldering is probably best. Those headers/duponts tends to slip out when you least want it.

replaced cable....worked once but switched to board usb ports (was using a usb hub)....and now its working fine!!!!! weird thing is.....already used usb hub with nanos and Uno...and all worked fine...only this (my first) pro mini having this issues Thanks you very much
