22 The \fBusb_other_speed_cfg_descr_t\fR configuration descriptor defines how
23 fields of a high speed device's configuration descriptor change if that device
24 is run at its other speed. Fields of this descriptor reflect configuration
25 descriptor field changes if a device's speed is changed from full to high
26 speed, or from high to full speed.
29 Please refer to Section \fI9.6.4\fR of the \fIUSB 2.0\fR specification. The
30 \fIUSB 2.0\fR specification is available at \fIwww.usb.org\fR.
33 This descriptor has the following fields:
37 uint8_t bLength Size of this descriptor,
40 uint8_t bDescriptorType Set to USB_DESCR_TYPE_OTHER_SPEED_CFG.
42 uint16_t wTotalLength Total length of data returned */
43 including all descriptors in
44 the current other-speed
47 uint8_t bNumInterfaces Number of interfaces in
48 the selected configuration.
50 uint8_t bConfigurationValue ID of the current other-speed
