On a hunch I've used USB pass-through to hand this device from my
Linux laptop host to a NetBSD 9 guest in a VirtualBox VM (b/c iirc,
that's how I successfully used it last time I needed to access ffs on
a CF card) and there:

  umass0 at uhub1 port 1 configuration 1 interface 0
  umass0: Generic (0x58f) Mass Storage Device (0x6362), rev 2.00/1.00, addr 2
  umass0: using SCSI over Bulk-Only
  scsibus0 at umass0: 2 targets, 4 luns per target
  sd0 at scsibus0 target 0 lun 0: <Generic, USB SD Reader, 1.00> disk removable
  sd0: drive offline
  sd1 at scsibus0 target 0 lun 1: <Generic, USB CF Reader, 1.01> disk removable
  sd1: drive offline
  sd2 at scsibus0 target 0 lun 2: <Generic, USB SM Reader, 1.02> disk removable
  sd2: drive offline
  sd3 at scsibus0 target 0 lun 3: <Generic, USB MS Reader, 1.03> disk removable
  sd3: drive offline

So there's something that goes askew in the initial autoconf attempt,
but I don't know anything about USB in general and our USB stack in
particular.
