It sees that there's a scsibus, but never finds a device:

umass0 at uhub3 port 1 configuration 1 interface 0
umass0: PNY Attache 2.0, rev 2.00/2.00, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target

And when I remove it:
umass0: at uhub3 port 1 (addr 2) disconnected
scsibus0 detached
umass0 detached


The 1.1 device appears at uhub2.
