Greg: The following series of patches documents a precise meaning for the URB_ISO_ASAP flag and implements the new definition in the ehci-hcd, uhci-hcd, and ohci-hcd drivers. Until now there has not been any clear-cut description of what the flag means, and different host controller drivers have implemented it in different ways. The new definition and implementation are suitable for the major users of isochronous transfers (the USB audio and video drivers).
