NAME
     usb_dev_descr - USB device descriptor

SYNOPSIS
     #include 


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

DESCRIPTION
     The usb_dev_descr_t device  descriptor  defines  device-wide
     attributes.  Please  refer  to  Section 9.6.1 of the USB 2.0
     specification. The USB 2.0  specification  is  available  at
     www.usb.org.


     The device descriptor is retrieved from a USB device  during
     device    enumeration    and    can    be    accessed    via
     usb_get_dev_data(9F).


     A device descriptor contains the following fields:

        uint8_t     bLength             Size of this descriptor,
                                         in bytes.

         uint8_t     bDescriptorType     Set to USB_DESCR_TYPE_DEV.

         uint16_t    bcdUSB              USB specification release
                                         number supported, in bcd.

         uint8_t     bDeviceClass        Class code (see below).

         uint8_t     bDeviceSubClass     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.

         uint16_t    idVendor            vendor ID value.

         uint16_t    idProduct           product ID value.

         uint16_t    bcdDevice           Device release number in
                                         binary coded decimal.
