i386, 7.0 (and PRERELEASE of 7.0), Xorg and Logitech G5 Laser mouse.

I have seen the same, or a similar, problem with my mouse a few, maybe
5, times this year. One time I had to reattach the mouse to another
usb port, and I believe I had a similar error message (host controller
process error). The other times I only had to detach and reattach the
mouse in the same usb port.

I have not been able to reproduce the problems.
