How to use the onboard USB port updated firmware
in GUI on windows
To ßash the Þrmware you have to enter the so called DFU mode. On Windows 10 I had to
use a tool called Zadig (download and start it) to be able to switch drivers for DFU mode
to work. In order to switch drivers you have to take the following steps.

• Push BOOT button on the ßight controller.
• Plug-in the USB cable (the red LED should not be as bright as normally).
• Fire up Zadig and hit “Options” and then “List All Devices”.
• From the list choose “STM32 BOOTLOADER”.
• Under “Driver” choose “WinUSB” on the right and hit “Reinstall Driver”.
• Close Zadig, disconnect the ßight controller, close all Google Chrome instances.
