Maybe the rt2800usb driver does not support changing interface type from
AP to station without requiring the interface to be set down first and
this could somehow get into state where the interface is assumed to be
disabled (and well, it is, for a very short moment). None of the drivers
I test with show this, so I would need to see full debug log to say why
this happens.
