[Bug 88746] Re: ehci_hcd module causes I/O errors in USB 2.0 devices

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)
