.LP
The \fBusb_other_speed_cfg_descr_t\fR 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 \fI9.6.4\fR of the \fIUSB 2.0\fR specification. The \fIUSB 2.0\fR specification is available at \fIwww.usb.org\fR.
