Most people are using a generic libusb-win32 driver for Ant+ dongles. I have two types, Garmin and Cycplus, and both show up as Dynastream as the manufacturer, but they do have minor differences, so even if the same chip from Dynastream, different configuration possibly.
In driver details, that shows up with the actual driver as libusb0.dll.
