This mailing list is for libusb-win32 under Windows which is compatible to
the libusb-0.1 API. It also covers libusbK and libusbdotnet.

For the cross-platofrom libusb-1.0 API, you should go to the libusb
mailing list.
    https://lists.sourceforge.net/lists/listinfo/libusb-devel

It seems that the request is not supported by the HID backend
(not so sure if it is a limitation or a bug), you should ask in
the libusb mailing list.

In any case, you may want to look at HIDAPI for cross-platform
HID support.
