usb_string_descr(9S)					    Data Structures for Drivers 				      usb_string_descr(9S)

NAME

       usb_string_descr - USB string descriptor

SYNOPSIS

       #include <sys/usb/usba.h>

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

DESCRIPTION

       The usb_string_descr_t string descriptor defines the attributes of a string, including size and Unicode language ID.  Other USB descriptors
       may have string descriptor index fields which refer to specific string descriptors retrieved as part of a device's configuration.

       Please refer to Section 9.6.7 of the USB 2.0 specification. The USB 2.0 specification is available at www.usb.org.

       A  string descriptor has the following fields:

	 uint8_t       bLength		      Size of this descriptor,
					      in bytes.

	 uint8_t       bDescriptorType	      Set to USB_DESCR_TYPE_STRING.

	 uint16_t      bString[1];	      Variable length Unicode encoded
					      string.

NAME

       usb_dev_qlf_descr - USB device qualifier descriptor

SYNOPSIS

       #include <sys/usb/usba.h>

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

DESCRIPTION

       The device qualifier descriptor usb_dev_qlf_descr_t defines how fields of a high speed device's device descriptor would look if that device
       is run at a different speed.  If a high-speed device is running currently at full/high speed, fields of this descriptor reflect how  device
       descriptor  fields  would  look	if speed was changed to high/full. Please refer to section 9.6.2 of the USB 2.0 specification. The USB 2.0
       specification is available at www.usb.org.

       A device descriptor contains the following fields:

	 uint8_t     bLength		 Size of this descriptor.

	 uint8_t     bDescriptorType	 Set to USB_DESCR_TYPE_DEV_QLF.

	 uint16_t    bcdUSB		 USB specification release
					 number in binary coded decimal.

	 uint8_t     bDeviceClass	 Device class code.
					 (See usb_dev_descr(9s).)

	 uint8_t     bDeviceSubClass	 Device 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.

	 uint8_t     bNumConfigurations  Number of available
					 configurations.

	 uint8_t     bReserved		 Reserved.
