    USB 3.0 Hub Changes · dbe79bbe
    John Youn authored
    Update the USB core to deal with USB 3.0 hubs.  These hubs have a slightly
    different hub descriptor than USB 2.0 hubs, with a fixed (rather than
    variable length) size.  Change the USB core's hub descriptor to have a
    union for the last fields that differ.  Change the host controller drivers
    that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
    use the union.
    
    Translate the new version of the hub port status field into the old
    version that khubd understands.  (Note: we need to fix it to translate the
    roothub's port status once we stop converting it to USB 2.0 hub status
    internally.)
    
    Add new code to handle link state change status.  Send out new control
    messages that are needed for USB 3.0 hubs, like Set Hub Depth.
    
    This patch is a modified version of the original patch submitted by John
    Youn.  It's updated to reflect the removal of the "bitmap" #define, and
    change the hub descriptor accesses of a couple new host controller
    drivers.
