Thrustmaster TS-XW RACER Manual página 7

IMPORTANT: DO NOT DISCONNECT your racing wheel from the USB port
without being prompted to do so, and DO NOT UNPLUG the racing wheel's
power supply during the firmware update!
Wait until the Firmware loading is complete: the Main Firmware progress bar must
be green all the way through.
The racing wheel self-calibrates (i.e. the wheel rim automatically rotates to the left
and right), and then its LED turns back on again.
