This is getting too confusing. :-( Let's try a simpler test. Leave USB_SUSPEND unset. First rmmod ohci-hcd. None of your full-speed USB devices will work, but that's okay. Try the suspend-twice test and see what happens. Second, rmmod ehci-hcd and modprobe ohci-hcd. Again try the suspend-twice test. Having only one USB host driver loaded at any time should simplify things.
