Additionally we have tested the program on two more different hubs. We haven't tested our 3.0 hub. Do you think there is any change to fall on a broken hub while running on a good host and make the error come to surface? Please mention if it has to be run on hubs.

You can now see the full picture, as said on the first message the subject must change because it is not intel specific. Intel though was consistent all their initial southbridges were broken while other vendors broke their good EHCI controller. Good luck with fixing, we can test any patch prior merging. Unfortunately one SiS 478 board died after POST and we couldn't test it so R.I.P until service! -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
