USB 1.0 IDE to ATAPI drive enclosure failure

Howdy list,

I'm running FreeBSD 5.1-RELEASE. I just bought a generic
USB 1.1/2.0/firewire external drive enclosure for my 32gb
Travelstar 2.0" 12.5mm hard drive.

The device shows up like this:

Nov 18 14:06:16 trevarthan kernel: umass0: Acer Labs USB 2.0 Storage Device, rev 2.00/1.03, addr 3
Nov 18 14:06:16 trevarthan kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Nov 18 14:06:17 trevarthan kernel: da0: <USB 2.0 Storage Device 0100> Fixed Direct Access SCSI-0 device
Nov 18 14:06:17 trevarthan kernel: da0: 1.000MB/s transfers
Nov 18 14:06:17 trevarthan kernel: da0: 30520MB (62506080 512 byte sectors: 255H 63S/T 3890C)

But `ls -al /dev/da*` reveals no slices:

crw-r-----  1 root  operator    4,  22 Nov 18 13:35 /dev/da0

The hard disk inside this enclosure was formatted with a 10gig
FAT32 partition. It works fine in a Coolmax Gemini 2.5" USB 2.0/1.1
drive enclosure (which shows up as IDE->ATA under Windows XP), and
it works fine in this enclosure as long as I'm running Windows XP
(but it shows up differently than the Gemini under XP: IDE-ATAPI).
It just doesn't work under FreeBSD 5.1-RELEASE or FreeBSD 4.8-RELEASE
for some reason...

I've found the following links relating to similar problems:

http://lists.freebsd.org/pipermail/freebsd-current/2003-August/008504.html

http://lists.freebsd.org/pipermail/freebsd-hardware/2003-July/000393.html

But no solutions. Has the USB code been updated since FreeBSD 5.1-RELEASE?
Is there a chance it will work if I cvsup to -CURRENT?

I contacted the gentleman from the first link above, and he said that
the only thing different about his configuration (other than hardware)
is that:

1.) He connects through a USB hub
2.) He runs -CURRENT from Nov 7th

I can't seem get my hands on a USB hub, so it looks like my only option is -CURRENT.

Does anyone have any clues to help get this drive working? I'm all for debugging
of any kind, including coding. I'm just not sure where to start.

Thanks!
