There is commit c04ee4b1136e (Revert "Revert "USB: EHCI: support
running URB giveback in tasklet context"") in Greg KH's usb-next tree.
Even with that commit, however, interrupts will remain disabled while
the completion handler is called. Changing that behavior is not so
easy, as quite a few drivers depend on it. There has been some work
done to change this, too. See the series of patches beginning here:
