Ok, so I gave up and went and bought a cheap used wireless router,
put an s/ftp server on the phone, ftp'ed the ssh key over and now
easily xfer to from the phone using sftp, etc.

However, since I put a fair amount of exercise into attempting USB
MTP and Bluetooth access and think I got pretty close, it would be
nice to go ahead and try to get those working also.

After spending some time with the Samsung Galaxy, I discovered that
in MTP mode it connects to ucom0 and in PTP mode to ugen0! However,
as:
  ugen0: SAMSUNG (0x4e8) SAMSUNG_Android (0x6866), rev 2.00/2.28, addr 3
not as:
  umodem0: SAMSUNG (0x4e8) SAMSUNG_Android (0x6860), rev 2.00/4.00, addr 3, iclass 2/2

Note the 0x6866 instead of 0x6860. libmtp includes entries for the
Samsung 0x6860 devices but not the 0x6866!  Ha.

So I might add the 0x6866 entry and recompile to see if it is
detected in PTP mode though I believe I really want MTP mode. But
not as a umodem/ucom device for libmtp's purposes. On reading the
code, it appears to me that libmtp only can use ugen devices though
I very well might have missed something.

Any thoughts? :^)
