The proprietary nature of the original software has led to a growing open-source movement. Projects like and r20x-usb-controller (on GitHub) are reverse-engineering the control protocols. Benefits of moving away from the official R20XCUSB software include:

Draws a minimal 100mA current directly from a standard 5V USB port . Core Functions of R20XCUSB Software
