Hi Greg, Here's a series of patches that add support for devices under hubs attached to an xHCI host controller. I already sent you the first patch to add interrupt transfer support, but you haven't queued it to your quilt tree so I sent it again. The next three refactoring patches were sent as part of the streams RFC, and are also needed for this hub patchset. I've tested these patches with full speed and high speed hubs, with various device combinations. I can't test with multi-TT hubs yet because the xHCI driver needs some work to handle alternate settings.
