NAME
       usb_dev_descr - USB device descriptor

SYNOPSIS
       #include <sys/usb/usba.h>

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.

	   uint8_t     iManufacturer	   Index of optional manufacturer
					   description string.
					   Valid if > 0.

	   uint8_t     iProduct 	   Index of optional product
					   description string.
					   Valid if > 0.

	   uint8_t     iSerialNumber	   Index of optional serial
					   number string.
					   Valid if > 0.

	   uint8_t     bNumConfigurations  Number of available
					   configurations.

	   Device descriptors bDeviceClass values:

	   USB_CLASS_PER_INTERFACE	   Class information is at
					   interface level.

	   USB_CLASS_COMM		   CDC control device class.

	   USB_CLASS_DIAG		   Diagnostic device class.

	   USB_CLASS_HUB		   HUB device class.

	   USB_CLASS_MISC		   MISC device class.

	   USB_CLASS_VENDOR_SPEC	   Vendor-specific class.

	   USB_CLASS_WIRELESS		   Wireless controller
					   device class.
