NAME

       usb_if_descr - USB interface descriptor

SYNOPSIS

       #include <sys/usb/usba.h>

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

DESCRIPTION

       The  usb_if_descr_t  interface descriptor defines attributes of an interface. A configuration contains one or more interfaces. An interface
       contains one or more endpoints.

       Please refer to Section 9.6.5 of the USB 2.0 specification. The USB 2.0 specification is available at www.usb.org.

       One  or	more  configuration  descriptors  are  retrieved  from	a  USB	device	during	device	enumeration.  They  can  be  accessed  via
       usb_get_dev_data(9F).

       A  interface descriptor has the following fields:

	 uint8_t     bLength		     Size of this descriptor
					     in bytes.

	 uint8_t     bDescriptorType	     Set to USB_DESCR_TYPE_IF.

	 uint8_t     bInterfaceNumber	     Interface number (0-based).

	 uint8_t     bAlternateSetting	     Alternate setting number for
					     this interface and its
					     endpoints (0-based).

	 uint8_t     bNumEndpoints	     Number of endpoints,
					     excluding endpoint 0.

	 uint8_t     bInterfaceClass	     Interface Class code
					     (see below).

	 uint8_t     bInterfaceSubClass      Sub class code. (See USB 2.0
					     specification of applicable
					     interface class for information.)

	 uint8_t     bInterfaceProtocol      Protocol code.  (See USB 2.0
					     specification of applicable
					     interface class for information.)

	 uint8_t     iInterface 	     Index of optional string
					     describing this interface
					     Valid if > 0. Pass to
					     usb_get_string_descr(9F) to
					     retrieve string.

	 USB 2.0 specification interface descriptor bInterfaceClass field
	 values are as follows:

		 USB_CLASS_APP		 Application-specific interface class

		 USB_CLASS_AUDIO	 Audio interface class

		 USB_CLASS_CCID 	 Chip/Smartcard interface class

		 USB_CLASS_CDC_CTRL	 CDC control interface class

		 USB_CLASS_CDC_DATA	 CDC data interface class

		 USB_CLASS_SECURITY	 Content security interface class

		 USB_CLASS_DIAG 	 Diagnostic interface class

		 USB_CLASS_HID		 HID interface class

		 USB_CLASS_HUB		 HUB interface class

		 USB_CLASS_MASS_STORAGE  Mass storage interface class

		 USB_CLASS_PHYSICAL	 Physical interface class

		 USB_CLASS_PRINTER	 Printer interface class

		 USB_CLASS_VENDOR_SPEC	 Vendor-specific interface class

		 USB_CLASS_WIRELESS	 Wireless interface class
