Make sure you are not running the 1.2 version firmware.  A UDev rule can 
stop them changing around.
I had a HVR4000 & Nova T that did this.  I found that they only changed 
order when I did a warm reboot.  Cold booting didn't change them.
Once the firmware gets loaded they must change the product or vendor ID 
and this causes them to be allocated in a different order by the OS.
