I think there are two sub-issues going on with this trouble attaching
USB mass storage devices to Ubuntu Server 10.04:

1) For our IOGear brand USB boxes, it is necessary to "wake up" Linux to
the drive's presence attached to a USB port. I tested a backup last
evening and it was speed-wise normal USB 2.0 expected performance.
Looking at the lsusb output, indeed it is showing up on the USB 2.0
controller bus. This is a workable situation.

2) For our client who happens to backup to Western Digital "My Passport
Essential" drives http://www.wdc.com/en/products/products.aspx?id=440 ,
the syntax specified by David Mitchell #7 does at least get the server
to see the drive, however in that case it runs (crawls) at USB 1.1
performance which is not acceptable.

This really needs to get fixed in 10.04, and preferably SOON. What
additional information could we provide to be of assistance?
