60# A helper method for implementing probe methods for PnP compatible
61# drivers. The driver calls this method with a list of PnP ids and
62# descriptions and it returns zero if one of the ids matches or ENXIO
63# otherwise.

65# If the device is not plug-and-play compatible, this method returns
66# ENOENT, allowing the caller to fall back to heuristic probing
67# techniques.
