USB_OTHER_SPEED_CFG_DESCR 9S "Jan 5, 2004"
NAME
usb_other_speed_cfg_descr - USB other speed configuration descriptor
SYNOPSIS
#include <sys/usb/usba.h>
INTERFACE LEVEL
illumos DDI specific (illumos 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.
