Non-Self-Identifying Devices

Devices that do not provide information to the system to identify themselves are called non-self-identifying devices. Drivers for these devices must have a probe(9E) routine that determines whether the device is really present. In addition, information about the device must be provided in a hardware configuration file (see driver.conf(4)), so that the system can provide probe(9E) with the information it needs to contact the device. See probe(9E) for more information.

A VMEbus device is an example of a non-self-identifying device. See vme(4) for more information.
