Question on how to get custom kernel module to work with udev

[Terry Barnaby <terry1@beam.ltd.uk>]

Hi,

I have a custom kernel device driver module for a PCI hardware device that I would like
to integrate with UDEV to get UDEV to generate the /dev nodes.

I am using Fedora Core 3.
I have not been able to make this work so far, so any ideas ?

When the device is loaded /sbin/hotplug is called with the environment:

export SUBSYSTEM=drivers
export DEVPATH=/bus/pci/drivers/admxrc2
export PATH=/sbin:/bin:/usr/sbin:/usr/bin
export ACTION­d
export PWD=/
export SHLVL=1
export HOME=/
export SEQNUMx5
export _=/bin/env

I have added a file /etc/udev/rules.d/40-admxrc.rules with the contents:

KERNEL="admxrc2", NAME="admxrcii%k"
SYSFS{vendor}="0x4144", NAME="admxrciii%k"

The two line are alternate versions for testing.

I have tried setting the udev config parameter "udev_log" to "yes" and
do get logs when other drivers are loaded. However when I do a
"rmmod admxrc2; modprobe admxrc2" no log information is printed.

1. Is there a way to get more debug information out of udev ?
2. Is there some special thing I need to do in the device module ?
3. Is there something wround with the configuration ?

Cheers

Terry
