I can not easily dump registers on the 2.6.31. I have recompile the old kernel and re-instrumented it. Well I don't find any important thing. The old kernel was using ehci_fsl.c basecode and the new one use chipidea. Let's say that some changes are in USB_CTRL usbmisc controller initialization but even play with those bits I did not find any failure on that side. I will continue on difference. Hope that some other have some idea ;).
