sysfs _should_ show you this, as it should point to the "parent" device, which will be associated with the ttyUSB interface. Well, both the tty device and the gpio device will have the same parent, is that good enough to determine this, or should the gpio device have the tty device as its parent? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
