But I never saw the problem with 2.6.26. That's puzzling me. Now I think the 3rd controller may be a client mode interface on the Geode LX, which I certainly don't use if it has such a thing. I know what EHCI and OHCI mean. I don't know what UDC is. I see mention of UDC under USB gadget support. I will try enabling that driver and see what it does. -- Len Sorensen -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
