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 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, and it works fine in this enclosure as long as
I'm running Windows XP. But it just doesn't want to work under
FreeBSD 5.1-RELEASE for some reason...

Does anyone have any clues to help get this drive working?
