Garmin Edge705: LUN1 of umass device not recognized

[poyopoyo at puripuri.plala.or.jp]

Hi,

I found I cannot see my Garmin Edge705 bike computer's storage through
USB as before. It has two umass devices in it: the first is internal
flash drive and the other is on board SD card slot and I lost the
latter now.

I managed to narrow down the responsible commit:

New Revision: 208911
URL: http://svn.freebsd.org/changeset/base/208911

Log:
  Implement the usage of Report Luns as part of SCSI probing for SCP3 or
  better devices. This can be disabled on a per-device basis using quirks as
  well.
  
  This also handles the case where there is actually no connected LUN 0
  (which can definitely be the case for storage arrays).

This is 19 months old commit so it affects both 10-CURRENT and
9.0-RELEASE. It seems so reasonable for LUN1 device going away when
LUN probing code is modified. :)

Could you tell me what can I do the next? Thanks.
