As suggested by Xiaofan firmware has two interfaces, with the second exposing no data endpoints of its own.
Opening the device using libusb_open_device_with_vid_pid and then enumerating the device using libusbx functions gets me the expected: ProductID: 0xA00A Interfaces: 2 Number of alternate settings: 1 Interface Number: 0 Number of endpoints: 2 Descriptor Type: 5 EP Address: 133 Descriptor Type: 5 EP Address: 6 Number of alternate settings: 1 Interface Number: 1 Number of endpoints: 0 What I don't get is how to write to the second interface. Using anything other than an index of 1 for libusb_claim_interface() returns LIBUSB_ERROR_NOT_SUPPORTED. I'm missing something crashingly obvious - can anyone point out what?
