USB2 enclosure doesn't work

[Daniel O'Connor]

I recently bought a "Laser" brand 2.5" drive enclosure and put an 80GB
WD disk in it and I can't get it working with FreeBSD (I tried 6.2 and 8.0).
It does work fine with Windows XP though.

I have another USB2 adapter (has 3.5" PATA, SATA and 2.5" PATA
connectors) and that works fine with FreeBSD.

The really weird thing is that I could fdisk even though fdisk
complained it could not write to it. I then read back the MBR and it was
changed. Just in case caching was involved I unplugged and replugged the
drive and the modified MBR was still there...

When I try to read or write to the disk dd just exits straight away with
no error (ie it got EOF on the first read/write).

Nothing unusual shows up in dmesg (eg no errors).

Here is what I see..
umass1: Super Top USB 2.0  IDE DEVICE, rev 2.00/2.01, addr 3
da4 at umass-sim1 bus 1 target 0 lun 0
da4: <WDC WD80 0BEVE-00UYT0 \\0000\\0000> Fixed Direct Access SCSI-0 device
da4: 40.000MB/s transfers
da4: 76319MB (156301488 512 byte sectors: 255H 63S/T 9729C)
umass1: at uhub4 port 8 (addr 3) disconnected
(da4:umass-sim1:1:0:0): lost device
(da4:umass-sim1:1:0:0): removing device entry
umass1: detached

I plan on giving it to my mother in law for christmas (she uses Windows..)
so I can test with it for a little while yet :)
