If you want to make the problem more likely to occur, just sleep for a 
few seconds in usb_add_hcd() after calling usb_hcd_request_irqs() and 
before calling hcd->driver->start().

Doing that both with and without the patch installed should show pretty 
quickly whether the patch does what you want.
