Could be. 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.
