Re: USB hotplug woes



Well I have since taken the complete plunge to 2.6. I was able to boot
debian by changing the fstab & grub configuration.

Ok so now I have researched on how to write udev.rules (using
http://www.reactivated.net/writing_udev_rules.html as reference).

In the guide at the bottom it recommends doing:

KERNEL=="sdb", RUN+="/usr/bin/my_program"

However what I am seeing in my /var/log/syslog (I modified
/etc/udev/udev.conf to output debug logging) is that it attempts to run the
script before it has actually done any of the volume discovery. My scripts
first command is to mount /dev/sdb1 to /mnt/usbkey. This doesn't work of
course since /dev/sdb1 wont be declared after the script is done.

Any ideas on what I can do from here?
