I thought so.  I think udev is great, it just needs slightly more helpful
documentation to make is really user accessible.  There are quite a few
"things to know" (such as the default PATH, which took awhile to
realize I was overlooking..).

I was thinking about changes to the How To Write UDev Rules document..

Yes, I noticed the target number changes even when the hardware remains
identical.

I thought I had a problem running path_id/usb_id to set those environment
variables (I don't remember which one sets them..), because the sysfs
entry was already gone.  I think I misunderstood, maybe the variables
are set from when the device was created? .. I'll look into again.  I'm
probably just confused, it's been a bit of mess building some
understanding.. :)

Thanks,
Richard
