Very odd indeed! I found a method to get the current kernel build to see
the USB HDD box! The command line program lsusb seems to wake the kernel
up to the fact that a USB HDD box is attached to the server. See the
following:

use...@hostname:~$ lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
use...@hostname:~$ lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 067b:3507 Prolific Technology, Inc. PL3507 ATAPI6 Bridge
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
use...@hostname:~$

The extra device in the second run is indeed the USB HDD box which the
first lsusb some how managed to get something to wake up and actually
see it.

Again these results are with the current build of the kernel: linux-
image-2.6.32-24-generic-pae_2.6.32-24.43_i386.deb

The syslog entries found the found USB HDD box are as follows:

Please let me know if there are more details which it would be helpful
to have in order to find a resolution to this problem.
