That's most peculiar.  Perhaps as of 1.6 the driver didn't know how to
make it handle oversize packets or some such?  This is now beyond my
competence - the diagnosis I offered seemed most probable to me in view
of the symptoms, but it is at odds with the implications of your code
snippet.  So I just don't know.
