Comment 341 for bug 88746

I think the problem is the suspend-mode implementation. Once your USB2.0 "thing" enters on suspend mode it can't wake up.
This state (suspend) is only especificated for 2.0 (ehci) nor 1.0/1.1

Disabling the autosuspend function, things work well, or disabling ehci function works well too. Sometimes, recompining kernel with noapic (disable global autosuspend functions) sometimes works well (I guess I read it before)
