Michael: I have been playing with this as well. Here is something for you to try as a workaround. I find that when I disable ehci, then re-enable it, I can see the USB key and the one high speed device I have (a Logitech C250 webcam) is found and driven with ehci driver. BTW, I'm using 10.04 desktop.

Here is the code sequence:

echo -n 0000:00:10.4 | sudo tee -a /sys/bus/pci/drivers/ehci_hcd/unbind

echo -n 0000:00:10.4 | sudo tee -a /sys/bus/pci/drivers/ehci_hcd/bind

(replace 0000:00:10.4 with whatever number is in /sys/bus/pci/drivers/ehci_hcd)

I grabbed this from http://ubuntuforums.org/showpost.php?p=8716597&postcount=4

This is still a bug, and a rather severe one in my opinion. It's not like this is some esoteric operation. I'm just trying to get a basic USB key to be recognized!
