These patches are against kernels 2.6.18 through at least 2.6.18-git7.
patch 15: This fix is not actually to ehci-hcd, but is rather a fix to
usbaudio necessitated by fixing the isoch underrun detection/reporting
in ehci. usbaudio playback nominally causes one, specific harmless
underrun in startup that the usbaudio code doesn't currently handle
properly.
