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.
