Installing USB driver on Windows

Most Bitcraze products using USB communication uses the libusb driver for Windows. This driver allows to communicate with USB devices without having to develop custom drivers. This page explains how to install the libusb driver using the Zadig tool.

Once windows is out of the way, launch Zadig, you should see your device in the list. Select the device, select libusb and click install:

The install process should run and succed. Installation is usually quick but it could also take some time:

Et voilà! The driver is now installed and you can use your USB Bitcraze device.

If the driver is wrongly installed and needs to be reinstalled or if Windows already have another driver installed for this device, plug the device, launch Zadig and click “Option/show all devices”. You should be able to choose the device in the list and reinstall the libusb driver. For example with the Crazyradio and the LPS node bootloader:

If you are having problems with the device not working all the time you can try to install the libUSBK driver, it have been behaving a bit better to some version of the Bitcraze softwares:
