    storage: Add quirks for Castlewood and Double-H USB-SCSI converters · 57cde01a

    Castlewood Systems supplied various models of USB-SCSI converter with their
    ORB external removable-media drive. The ORB Windows and Macintosh drivers
    support six USB IDs:
     084B:A001     [VID 084B is Castlewood Systems]
     04E6:0002 (*) ORB USB Smart Cable P/N 88205-001 (generic SCM ID)
     2027:A001     Double-H Technology DH-2000SC
     1822:0001 (*) Ariston iConnect/iSCSI
     07AF:0004 (*) Microtech XpressSCSI (25-pin)
     07AF:0005 (*) Microtech XpressSCSI (50-pin)
    
    *: quirk already in unusual-devs.h
    
    [Apparently the official VID for Double-H Technology is 0x07EB = 2027
    decimal. That's another hex/decimal mix-up with these SCM-based products
    (in addition to the Ariston and Entrega ones). Perhaps the USB-IF informed
    companies of their allocated VID in decimal, but they assumed it was hex?
    It seems all Entrega products used VID 0x1645, not just the USB-SCSI
    converter.]
    
    Double-H Technology Co., Ltd. produced a USB-SCSI converter, model
    DH-2000SC, which is probably the one supported by the ORB drivers. Perhaps
    the Castlewood-bundled product had a different label or PID though?
    Castlewood mentioned Conmate as being one type of USB-SCSI converter.
    Conmate and Double-H seem related somehow; both company addresses in the
    same road, and at one point the Conmate web site mentioned DH-2000H4,
    DH-200D4/DH-2000C4 as models of USB hub (DH short for Double-H presumably).
    Conmate did show a USB-SCSI converter model CM-660 on their web site at one
    point. My guess is that was identical to the DH-2000SC.
    
    Mention of the Double-H product:
      http://web.archive.org/web/20010221010141/http://www.doubleh.com.tw/dh-2000sc.htm
    The only picture I could find is at
      http://jp.acesuppliers.com/catalog/j64/component/page03.html
    The casing design looks the same as my ORB USB Smart Cable which has ID
    04E6:0002.
    
    Anyway, that's enough rambling. Here's the patch.
    
    storage: Add quirks for Castlewood and Double-H USB-SCSI converters
    
    Add quirks for two SCM-based USB-SCSI converters which were bundled with
    some Castlewood ORB removable drives. Without the quirk only the (single)
    drive with SCSI ID 0 can be accessed.
