Subject: 2.6.31 ehci problem - mouse dead on scroll
Hi,
I have a nice logitech wireless mouse. With 2.6.30 and earlier it works well.
With 2.6.31 it sometimes kills the ehci bus, if I scroll too fast. Very slow
scrolling is ok, not scrolling is ok. Fast scrolling, bus is dead and dmesg
looks like this:

and the only thing to get the mouse back is rmmod ehci_hcd modprobe ehci_hcd.
It does not happen everytime - of course always if it is most annoying and
never when I really don't care ;)
mouse is attached to a 4port revoltec disk usb 2.0 hub with an external power
brick.
When I want to attach the mouse directly, I have to load ohci_hcd FIRST. AND
after that lsusb just hangs, but I seem to be able to scroll as much as I
want.
