Update:
Here is what happens with 2.5.61:
This is tested on the system with off the shelf parts.
1. OHCI loaded, USB-2.0 parts.
Everything works.
2. Remove 2.0 parts & replace with 1.1 parts.

3. Unplug, shuffel parts & replug.
Everything works. 10 times.
4. Remove 1.1 parts & replace with 2.0 parts.
Everything works.
5. Do step 2 again

6. DO step 3 again.
Everything works.
7. This is what I get when I unplug &replug a part.

AM I causing the bad hash, because /sbin/hotplug isn't there.
I thought I'd try unloading & reloading the usb subsystem, to get some more info.
Using module-init-tools-0.7
./rmmod -f ohci_hcd (OK)
./rmmod -f uhci_hcd (OK)
umount /proc/bus/usb (OK)
./rmmod -f usbcore ( HANGS )
I'll try some more tests on the other system, tomorrow.
Thanks,
