Variables

bDescriptorType ubyte bDescriptorType;: Descriptor type. Will have value * \ref libusb_descriptor_type::LIBUSB_DT_DEVICE_CAPABILITY * LIBUSB_DT_DEVICE_CAPABILITY in this context.
bDevCapabilityType ubyte bDevCapabilityType;: Capability type. Will have value * \ref libusb_capability_type::LIBUSB_BT_SS_USB_DEVICE_CAPABILITY * LIBUSB_BT_SS_USB_DEVICE_CAPABILITY in this context.
bFunctionalitySupport ubyte 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.
bLength ubyte bLength;: Size of this descriptor (in bytes)
bU1DevExitLat ubyte bU1DevExitLat;: U1 Device Exit Latency.
bU2DevExitLat ushort bU2DevExitLat;: U2 Device Exit Latency.
bmAttributes ubyte 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 \ref libusb_ss_usb_device_capability_attributes.
wSpeedSupported ushort wSpeedSupported;: Bitmap encoding of the speed supported by this device when * operating in SuperSpeed mode. See \ref libusb_supported_speed.
