Log message:
The NCM encoding allows to aggregate multiple segments in one single
transfer. Using wMaxSegmentSize for bulk-in could break the rx-path
because xfer length can be smaller than the messages sent by the device.
And using some constant value for rx/tx size is also a bad idea, because
we might be sending messages to the device that are too big for it to
handle them. Therefore use the NCM GET_NTB_PARAMETERS request to query
the device's configuration.
