I think there's a physical problem with your USB controllers. Yes, it is
exceptional, but it does happen on rare occasions.
If you want to do some more testing, you can try this: Turn on USB
verbose debugging and Debug filesystem in the kernel configuration
(CONFIG_USB_DEBUG and CONFIG_DEBUG_FS) and rebuild the kernel. Then after
booting, do
mount -t debugfs none /sys/kernel/debug
cd /sys/kernel/debug/uhci
With your hard disk plugged in and turned on, make a copy of the files in
that directory and post the copies.
