Just base the udev rules off of the devices serial numbers: Here's a
snippet from my MBE's udev rules (which hosts 2 of my hdpvrs)

[code]
KERNEL=="video[0-9]*", ATTRS{product}=="Hauppauge HD PVR",
ATTRS{serial}=="00A46253", SYMLINK+="hdpvr1", RUN
+="/sbin/hdpvr-install.sh"
KERNEL=="video[0-9]*", ATTRS{product}=="Hauppauge HD PVR",
ATTRS{serial}=="00A40C31", SYMLINK+="hdpvr2", RUN
+="/sbin/hdpvr-install.sh"
[/code]

Of course, you probably don't need to run the script... that was put in
place way back to correct the hue/saturation issue with the latest
firmware and older kernels... I've been informed its since been
corrected, but I still let the script do its thing - it hasn't hurt
anything yet :-)

Cheers,

Andrew.
