NAME
     usb_dev_qlf_descr - USB device qualifier descriptor

SYNOPSIS
     #include 


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

DESCRIPTION
     The device qualifier descriptor usb_dev_qlf_descr_t  defines
     how  fields of a high speed device's device descriptor would
     look if that device is run  at  a  different  speed.   If  a
     high-speed  device  is running currently at full/high speed,
     fields of this  descriptor  reflect  how  device  descriptor
     fields  would look if speed was changed to high/full. Please
     refer to section 9.6.2 of the USB 2.0 specification. The USB
     2.0 specification is available at www.usb.org.


     A device descriptor contains the following fields:

       uint8_t     bLength             Size of this descriptor.

       uint8_t     bDescriptorType     Set to USB_DESCR_TYPE_DEV_QLF.

                                       number in binary coded decimal.

       uint8_t     bDeviceClass        Device class code.
                                       (See usb_dev_descr(9s).)

       uint8_t     bDeviceSubClass     Device subclass code.(See
                                       USB 2.0 specification of
                                       applicable device class for
                                       information.)

       uint8_t     bDeviceProtocol     Protocol code.(See
                                       USB 2.0 specification of
                                       applicable device class for
                                       information.)

       uint8_t     bMaxPacketSize0     Maximum packet size of
                                       endpoint 0.

       uint8_t     bNumConfigurations  Number of available
                                       configurations.

       uint8_t     bReserved           Reserved.
