NAME
usbotherspeedcfgdescr - USB other speed configuration
descriptor
SYNOPSIS
#include
INTERFACE LEVEL
Solaris DI specific (Solaris DI)
DESCRIPTION
The usbotherspeedcfgdescrt 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:
uint8t bLength Size of this descriptor,
in bytes.
uint8t bDescriptorType Set to USBDESCRTYPEOTHERSPEDCFG.
uint16t wTotalLength Total length of data returned */
including all descriptors in
the current other-speed
configuration.
uint8t bNumInterfaces Number of interfaces in
the selected configuration.
uint8t bConfigurationValue ID of the current other-speed
configuration (1-based).
uint8t iConfiguration Configuration value.
Valid if > 0. Pass to
usbgetstringdescr(9F)
to retrieve string.
uint8t bmAttributes Configuration characteristics
[See usbcfgdescr(9S).]
uint8t bMaxPower Maximum power consumption
in 2mA units.
