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.

NAME

       usb_cfg_descr - USB configuration descriptor

SYNOPSIS

       #include <sys/usb/usba.h>

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

DESCRIPTION

       The usb_cfg_descr_t configuration descriptor defines attributes of a configuration. A configuration contains one or more interfaces. A con-
       figuration descriptor acts as a header for the group of other descriptors describing the subcomponents (for example,  interfaces  and  end-
       points)	of  a  configuration.  Please  refer  to  Section  9.6.3  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 configuration descriptor has the following fields:

       uint8_t	       bLength		       Size of this descriptor
					       in bytes.

       uint8_t	       bDescriptorType	       Set to USB_DESCR_TYPE_CFG.

       uint16_t        wTotalLength	       Total length of data returned
					       including this and all other
					       descriptors in this configuration.

       uint8_t	       bNumInterfaces	       Number of interfaces in this
					       configuration.

       uint8_t	       bConfigurationValue     ID of this configuration
					       (1-based).

       uint8_t	       iConfiguration	       Index of optional configuration
					       string. Valid if > 0.

       uint8_t	       bmAttributes	       Configuration characteristics
					       (See below).

       uint8_t	       bMaxPower	       Maximum power consumption, in
					       2mA units.

       Configuration descriptors define the following bmAttributes:
	    USB_CFG_ATTR_SELFPWR       -      Set if config not using bus power.
	    USB_CFG_ATTR_REMOTE_WAKEUP -      Set if config supports rem wakeup.
