You can use the Clubsport USB Adapter in Shifter, Handbrake or Pedal mode. This video tutorial shows you how to flash the right firmware and explains how to calibrate the shifter afterwards:
The ClubSport Shifter needs to be calibrated before first use, no matter to which device (USB Adapter, Wheel Base) you connect it. The calibration will be stored inside this device and not inside the shifter. After the firmware of a wheel base or of the ClubSport Shifter is updated, the calibration would have to be re-done.
