Type: USBDeviceQualifierDescriptor
Alternate device descriptor indicating the capabilities of the device
in full-speed, if currently in high-speed; or in high-speed, if it is
currently in full-speed. Only relevant for devices supporting the
high-speed mode.
Variables:
bLength - Size of the descriptor in bytes.
bDescriptorType - Descriptor type (<USBDESC_DEVICE_QUALIFIER>).
bcdUSB - USB specification release number (in BCD format).
bDeviceClass - Device class code.
bDeviceSubClass - Device subclass code.
bDeviceProtocol - Device protocol code.
bMaxPacketSize0 - Maximum packet size of endpoint 0.
bNumConfigurations - Number of possible configurations for the device.
bReserved - Reserved.
