\nDescription
\nGets a USB descriptor. Convenience functions exist to simplify\n getting some types of descriptors. Use\n-usb_get_string() or usb_string() for USB_DT_STRING.\n+usb_get_string() or usb_string() for USB_DT_STRING.\n Device (USB_DT_DEVICE) and configuration descriptors (USB_DT_CONFIG)\n are part of the device structure.\n In addition to a number of USB-standard descriptors, some\n devices also use class-specific or vendor-specific descriptors.
This call is synchronous, and may not be used in an interrupt context.
\nReturn
\nThe number of bytes received on success, or else the status code\n returned by the underlying usb_control_msg() call.
returns UTF-8 version of a string descriptor
