_ftdi_determine_max_packet_size() first looks at the device and then at
descriptor.endpoint[0].wMaxPacketSize. The latter is taken uncinditionally,
but if it is not found or the way to read it is not found, the chip default
is taken.
I suspect FreeBSD behaves other than our code expects and so we keep the
default on FreeBSD. Some print message after
packet_size = descriptor.endpoint[0].wMaxPacketSize;
could confirm.
