A structure representing the SuperSpeed USB Device Capability descriptor This descriptor is documented in section 9.6.2.2 of the USB 3.0 specification.
All multiple-byte fields are represented in host-endian format.
uint8_t libusb_ss_usb_device_capability_descriptor::bDescriptorType |
Descriptor type.
Will have value libusb_descriptor_type::LIBUSB_DT_DEVICE_CAPABILITY LIBUSB_DT_DEVICE_CAPABILITY in this context.
uint8_t libusb_ss_usb_device_capability_descriptor::bDevCapabilityType |
Capability type.
Will have value libusb_capability_type::LIBUSB_BT_SS_USB_DEVICE_CAPABILITY LIBUSB_BT_SS_USB_DEVICE_CAPABILITY in this context.
uint8_t libusb_ss_usb_device_capability_descriptor::bmAttributes |
Bitmap encoding of supported device level features.
A value of one in a bit location indicates a feature is supported; a value of zero indicates it is not supported. See libusb_ss_usb_device_capability_attributes.
uint16_t libusb_ss_usb_device_capability_descriptor::wSpeedSupported |
Bitmap encoding of the speed supported by this device when operating in SuperSpeed mode.
uint8_t libusb_ss_usb_device_capability_descriptor::bFunctionalitySupport |
The lowest speed at which all the functionality supported by the device is available to the user.
For example if the device supports all its functionality when connected at full speed and above then it sets this value to 1.
