The FragnStein and Xscorch can be upgraded with the firmware software , you will need to install the driver to get the device work with your PC. Our Drivers are IBM PC compatible for windows XP, Vista32/64bit, Windows7 32/64bit.
Anytime you are going to use the firmware and config software , you will have to put the RF Reciever into the computer USB port while holding the Reciever button.
Release the Reciever button as soon as the Reciever is in the USB port. This allows the Reciever to be identified in Setup mode.
FragnStein and Xscorch don't need driver when you use them as PC mouse.
