Interpret that firmware version as "7.15g" for Seagate purposes.  As far as I
know, all Scorpion-class drives support sync.

Here's an example of what a Diamondback changer would look like:

    Host: scsi0 Channel: 00 Id: 06 Lun: 00
      Vendor: ARCHIVE  Model: Python 28849-XXX Rev: 4.CM
      Type:   Sequential-Access                ANSI SCSI revision: 02
    Host: scsi0 Channel: 00 Id: 06 Lun: 01
      Vendor: ARCHIVE  Model: Python 28849-XXX Rev: 4.CM
      Type:   Medium Changer                   ANSI SCSI revision: 02

This is major version "4" of the firmware, which also supports sync.  (The
unusual "4.CM" indicates that this particular drive has OEM firmware.)
