I too am having this problem but with a Kingston DataTraveler Elite 1GB 
usb drive.

In the dmesg of 6.0 CURRENT from Dec 22 I get:

Which is a little different from the OP.

But in a stock NetBSD 2.0 it works as shown below.

NetBSD 2.0 (GENERIC) #0: Wed Dec  1 10:58:25 UTC 2004
builds at build:/big/builds/ab/netbsd-2-0-RELEASE/i386/200411300000Z-obj...
    /big/builds/ab/netbsd-2-0-RELEASE/src/sys/arch/i386/compile/GENERIC
umass0 at uhub3 port 5 configuration 1 interface 0
umass0: Kingston DT Elite HS 2.0, rev 2.00/2.00, addr 4
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <Kingston, DT Elite HS 2.0, 5.02> disk 
removable
sd0: 1002 MB, 844 cyl, 128 head, 19 sec, 512 bytes/sect x 2052607 sectors
umass0: at uhub3 port 5 (addr 4) disconnected
sd0 detached
scsibus0 detached
umass0 detached

If it is any help, it may work in NetBSD 2.0 which might provide a basis 
of code to be ported over to FreeBSD.

To get mine to work, I will have to wait for the port over as I am a newbie.

Thanks
