Subject: [PATCH 06 of 11] USB hub driver update

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
