ARM64-based Machines
ARM64-based machines require different drivers, but we do support the cross-platform Microsoft driver (WinUSB). The existing driver (libusb0.1) doesn’t work, however, we have a UWP version of ant-lib which uses WinUSB. There is a beta version of it up on the website, located here:
