 +==== Improving Communication performance - disconnect USB ====
 +
 +The main board has a native USB connector on the side of the hand used for firmware update.
 +
 +It is **highly recommended** that users **disconnect the USB cable on the side of the hand, when in normal operation**.
 +
 +This happens because the USB port is handled by the main ARM Cortex processor. As the USB stack is fairly heavy in terms of interruptions and stealing processing time, having the USB cable connected to the hand (and computer) slows down performance as the processor needs to be handling the regular polling from the PC. \\
 +(even if not using any application on the PC side, the fact that the cable is connected, generates overhead between the PC and the hand)
