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_other_speed_cfg_descr - USB other speed configuration descriptor

SYNOPSIS

       #include <sys/usb/usba.h>

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

DESCRIPTION

       The  usb_other_speed_cfg_descr_t  configuration	descriptor  defines how fields of a high speed device's configuration descriptor change if
       that device is run at its other speed. Fields of this descriptor reflect configuration descriptor field changes	if  a  device's  speed	is
       changed from full to high speed, or from high to full speed.

       Please refer to Section 9.6.4 of the USB 2.0 specification. The USB 2.0 specification is available at www.usb.org.

       This descriptor has the following fields:

       uint8_t	     bLength		     Size of this descriptor,
					     in bytes.

       uint8_t	     bDescriptorType	     Set to USB_DESCR_TYPE_OTHER_SPEED_CFG.

       uint16_t      wTotalLength	     Total length of data returned */
					     including all descriptors in
					     the current other-speed
					     configuration.

       uint8_t	     bNumInterfaces	     Number of interfaces in
					     the selected configuration.

       uint8_t	     bConfigurationValue     ID of the current other-speed
					     configuration (1-based).

       uint8_t	     iConfiguration	     Configuration value.
					     Valid if > 0. Pass to
					     usb_get_string_descr(9F)
					     to retrieve string.

       uint8_t	     bmAttributes	     Configuration characteristics
					     [See usb_cfg_descr(9S).]

       uint8_t	     bMaxPower		     Maximum power consumption
					     in 2mA units.
