Using a hub -- a 2.0 hub, I think -- connected to a USB 2.0 port,
I tried using a 1.1 USB flash disk.  The following messages appeared:


ehci0: *** WARNING: opening low/full speed device, this does not work yet.
umass0 at uhub5 port 3 configuration 1 interface 0
umass0: M-Systems DiskOnKey, rev 1.00/2.00, addr 3
umass0: using SCSI over Bulk-Only
ehci0: *** WARNING: opening low/full speed device, this does not work yet.
umass0: cannot open 1-out pipe (bulk)

Is this unsupported?  Here's the messags for the hub itself:

uhub5 at uhub4 port 7
uhub5: NEC Corporation USB2.0 Hub Controller, class 9/0, rev 2.00/1.00, addr 2
uhub5: single transaction translator
uhub5: 4 ports with 4 removable, self powered
