What I haven't reported was that I did find in a bootup section of the 
log, and odd looking reference to hpfax from the trinity install, which 
I reported to the trinity list.  And the reply there was to rename it, 
and if that solved the problem, then nuke it.  I renamed it to hpfox 
last Wednesday, and have had no further trouble with the whole usb tree 
dying since. This is Monday already.

its  part of hplip, but its like N-M, its been relinked and can't be 
removed without taking the whole desktop with it.

So in order to run a dhcpd free host file system which is what I have 
done here for much of 30 years going clear back into my Amiga days, 
using static defined addresses for all the local net, the only thing you 
can do to stop N-M from tearing down a working network is to setup 
the /e.n/i.d/whatever name with the correct static data, and immediately 
chattr +i it so N-M can't tear it down, ditto for the link called 
resolv.conf. Nuke it, touch a real file by that name then edit the 
nameserver stuff into it, and chattr +i it, again so N-M can't tear it 
down. When N-M has been made to leave a net setup labeled "static" alone 
I'll certainly celebrate. But that hasn't happened in the armbian world 
yet.

So unless you make a living sending faxes, rename hpfax to something 
else, others have had the same problems with it. IOW.its a knowm 
troublemaker. So now it has been reported. FWIW, my cpu is running 10C 
cooler too.
