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)
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!
