Hi,
Here's a patch against 2.5.3-pre1 for the USB hub driver that keeps an
error message from happening when a device is removed from the system
(happens as part of the handoff from a USB 2.0 to 1.1 controller for a
slow/full speed device.) This patch was written by David Brownell.
thanks,
greg k-h
