I've merged the latest master (dd9c154). The UASP driver saw the following update:

    [USB] UASP: Unlock device after reset; EP updates
    
    * Unlock the device after reset.
    
    * Initialize urb->ep directly. struct
      uasp_tport_info already records the struct
      usb_host_endpoint which makes it easy to
      directly initialize urb->ep. This anticipates
      when drivers would have to initialize the ep in
      the urb directly as opposed to the USB core
      having to use pipes.
    
    * Use the UAS pipe macros throughout the code for
      endpoint indexes.

The branch can be found here off of master:
