Tell me, what happens if you leave that patch installed, and you use the patch I sent last week (the one that removes a chunk of code from ohci-hub.c), and you also set CONFIG_USB_SUSPEND?
I think the real underlying problem here is that David's implementation of root-hub suspend in ohci-hcd is incompatible with the overall scheme I've been working on. In the end I'll probably have to rewrite the ohci-hcd code.
