USB2 works just fine with 1.6 at least. I've got an external 3.5" IDE->
USB2 enclosure (marked ADSTech on the case, see
for product info).
It shows up as:
umass0 at uhub3 port 4 configuration 2 interface 0
umass0: DMI USB 2.0 Storage Adaptor, rev 2.00/11.10, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 luns per target
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 1 lun 0: <WDC WD12, 00JB-75CRA0, 16.0> SCSI0 0/direct fixed
sd0: 111 GB, 114440 cyl, 64 head, 32 sec, 512 bytes/sect x 234375000 sectors
Performance wise, I get well over 10MByte/sec writing to it (I use it for
backups), so it's perfectly acceptable WRT performance for my needs. ;-)
