I remember that the Windows HID backend does not yet support
HID Collections. Is this still true since it is not listed in the known
restrictions.
https://github.com/libusbx/libusbx/wiki/Windows-Backend#wiki-Known_Restrictions

Before the HID removal, the libusb.org Windows backend Wiki
listed the following limitation.
http://www.libusb.org/wiki/windows_backend?version=181
"Multiple HID top level collections are currently not supported
(only the first top level collection will be used)."
