 Log Message:
 usb(9): Record config index, not just number, in struct usbd_device.
 
 The index is a zero-based index in [0, bNumConfigurations), or -1 for
 unconfigured.
 
 The number is an arbitrary value of a config descriptor's
 bConfigurationValue field, or 0 for unconfigured -- with the tricky
 caveat that bConfigurationValue might also be 0.
