A structure representing the superspeed endpoint companion descriptor.
This descriptor is documented in section 9.6.7 of the USB 3.0 specification. All multiple-byte fields are represented in host-endian format.
| uint8_t libusb_ss_endpoint_companion_descriptor::bDescriptorType |
Descriptor type.
Will have value libusb_descriptor_type::LIBUSB_DT_SS_ENDPOINT_COMPANION in this context.
| uint8_t libusb_ss_endpoint_companion_descriptor::bMaxBurst |
The maximum number of packets the endpoint can send or recieve as part of a burst.
| uint8_t libusb_ss_endpoint_companion_descriptor::bmAttributes |
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
| uint16_t libusb_ss_endpoint_companion_descriptor::wBytesPerInterval |
The total number of bytes this EP will transfer every service interval.
valid only for periodic EPs.
