Stuart Hayes here at Dell has identified this or/and mix-up in the
ehci-hcd driver.  Because of this, ehci-hcd is not properly released by
BIOSes supporting full 2.0 and port behavior can then become erratic.

(Code predates general availability of such BIOS firmware.  This version
of the patch also fixes minor linewrap issues.)
