To install the USB driver for a ROBO TX Controller do the following:
1. Connect ROBO TX Controller to a PC by means of the USB cable.
2. Power on ROBO TX Controller.
3. If it is the first time when ROBO TX Controller is powered on being connected to this USB port of a PC, then
   Windows will ask for the driver for a new USB device. Automatic installation should be refused. Windows should
   be informed instead to use the file "ROBO_TX_Controller.inf" from this directory. This file contains information
   for Windows about how to install the driver. After finishing installation of the driver, a new COM port with the
   name "fischertechnik USB ROBO TX Controller" should appear in the Windows Device Manager.
