Or, does a 4.6 kernel need to be > configured differently if you want USB? Are you sure you configured in the correct host controller that you want? Have you done a diff of your .config files to see what you changed? How did you create your 4.6 config? thanks, greg k-h -- 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
