Descriptor type. Will have value * \ref libusb_descriptor_type::LIBUSB_DT_SS_ENDPOINT_COMPANION in * this context.
Size of this descriptor (in bytes)
The maximum number of packets the endpoint can send or * recieve as part of a burst.
In bulk EP: bits 4:0 represents the maximum number of * streams the EP supports. In isochronous EP: bits 1:0 * represents the Mult - a zero based value that determines * the maximum number of packets within a service interval
