Windows Prerequisites

The device driver for your ANT+ usb stick needs to be updated to be compatible with the Node usb and ant-plus modules. This updated driver is partially backwards compatible and will break some functionality in existing applications such as Zwift (calibrating ANT+ FE-C devices becomes unavailable for example).

Install

1. Download and run Zadig
2. With Zadig open select Options -> List All Devices
3. In the device drop down select your ANT+ usb stick device
4. Toggle the driver selector to "libusb-win32". Selecting "libusb-win32" is very important to retain partial compatibility with other applications.
5. Click either the "Replace Driver", "Downgrade Driver" or "Reinstall Driver" button to complete the installation.

Uninstall

To reinstall the original ANT+ usb drivers and restore full functionality in other software follow these steps:

1. Open the Device Manager
2. Expand the "libusb-win32 devices" option.
   
3. Right click on your ANT+ usb device and select "Uninstall Device"
4. On the following dialog box click "Delete the driver software for this device"
   
5. Click "Uninstall" to complete the process
