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.

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.
