[Info-vax] USB disk enclosures

   The point there was that the USB adapter card worked, and
so the problem was probably in the USB-SATA adapter in the
external disk enclosure, not in the USB adapter card in the
system itself.

   So the value of your advice may be how great, exactly?

   I do some USB stuff, and my guess is that every instance
of the USB-SATA adapter presents the same ID info to the
system, rather than passing along some ID which is based on
the disk drive which is hiding behind that USB-SATA adapter. 
Thus, the VMS USB manager (UCM = USB Configuration Manager)
sees every one of them as the same device.

   The closest thing I have to such devices is a WD My Book. 
Because I have only one of them, and I don't want to lose the
data thereon, I can't run any useful tests with it.  Perhaps
a USB-SATA adapter from a different vendor would present a
different ID from the first type, which would not be as good
as an ID which depends on the actual disk ID, but might be
better than a second, twin ID.
