Without this patch, the driver won't check that the last fully-occupied uframe for a new split transaction was vacant beforehand. This can lead to a situation in which the first 188 bytes of a 192-byte isochronous transfer are scheduled in the same uframe as an existing interrupt transfer. The resulting schedule looks like this: uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT uframe 1: 4-byte isoc-OUT SSPLIT The SSPLITs are intermingled, causing an error in the downstream hub's TT. If you are having problems with devices or hub ports resetting, or failed interrupt transfers, when you start using a USB audio or video (Isochronous) device, this patch may help.
