This is probably unrelated to your problem, but here's my experience...

I had a problem in Hardy with my external USB hard drive no longer
mounting after a security update. I found I could get it to mount by
inducing USB activity, such as powering on my USB scanner, printing,
etc.

At the time I was using a PS/2 keyboard; when I switched to a USB
keyboard the problem went away.

I think I read that the problem was subsequently fixed (presumably in
Intrepid or Jaunty).
