NAME
     usb_other_speed_cfg_descr - USB  other  speed  configuration
     descriptor

SYNOPSIS
     #include 


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.
