There are 2 things required for the probe function to be called: a device and a driver. Normally, the architecture portion of the kernel registers devices for all of the device that it has. Then when you register a driver, it will detect if a device with a matching name has been registered. If it finds a match, it will call the probe routine. I normally work with linux in an embedded environment (ARM and MIPS), not programming for linux under x86, so its possible that things happen a little differently in that environment. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
