Do you have CONFIG_TRACE enabled? If not, that patch should have no affect on your system. If you do have it enabled, this change causing a lack of USB device connection seems very strange, and I really don't understand what is going on. If you manually revert that patch, does your problem go away? I wonder if it's really a timing issue somewhere... 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
