which means the hub detects a device, and tries to configure it.

The root hub is virtual and implemented in SW. It detects the device any time there's a pull-up on one of the D+ or D- lines, no matter if controller is working properly or not.

second: the device is happy to see a request and replies correctly.... but there's no interrupt fired, whether using SUI_INT_USB (==11) or the SCC3 interrupt (==42)

Make sure you've adopted the following functions to your board:
   static int board_configure(struct m8xxhci_private *hp)
   static int setup_usb_clock(struct m8xxhci_private *hp)
so the controller will get proper USB clock.
