#196936 — Insertion of USB devices not being recognised.

As per subject, after the last image upgrade, the computer doesn't
recognise when a USB device is plugged into a USB socket.
what is the problem?

System is Debian Stretch V9.4
dragonfly 4.9.0-6-amd64 #1 SMP Debian
4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU

Rebooting with the device plugged in does not "locate" the device.
I've used fuser and lsof on both device and directories where the
devices are normally mounted to no benefit.

The only USB devices that are recognised are keyboard, mouse and raid
array on USB3.0.

If you run "journalctl -f" as root and then plug in the device, is 
anything logged?

Nothing, but AIUI that is systemd logging and systemd crapped itself
months ago and I'm running only on sysvinit.

"sudo tail dmesg" logs nothing either

what does raid array has to do with USB3.0?
what is your use case exactly?

software raid through USB port to case carrying five hard disks.
It isn't mounted in /etc/fstab and i usually type the mounting string
when I need access.

what do you see in dmesg when you plug in the device?
What happens if you downgrade the kernel to the previous version?

Nothing. that was the problem. it is hard to mount it if you don't know
what /dev/sd?? it is and although I "know" what it should be, unless it
is listed in dmesg, i can do nothing with it,

> What happens if you downgrade the kernel to the previous version?
Same situation, but it lead me to an unwelcome diagnose.
i extracted the machine and the back plane ports were working. so I
went back t 9.0.6(?) and it was the same.

The current diagnose is that the front usb ports have failed for data.
they work fine for power(mobile phone charging), but not for data.

Not impressed as the mobo is less than two years old.

Thanks for the help

My suggestion is late, and possibly not much of a contribution due 
to my not having read the entire thread.

I have two motherboards which BIOS settings which allow the 
front-side USB ports to be set for charging only. Is there any 
possibility that such a setting is in effect on your motherboard?

Idea welcome and I'll check it out.
The mobo manual talks about option to enable/disable individual usb
ports, but the reason(s) for this to be the cause for is ???

They're a security threat.

I was thinking about why it would switch off on my machine, but OTOH I
was once directed to go around a office and remove all trhe floppy
drives(when floppy drives = sneaker net) for the same reason. that was
an interesting period of office politics.

I thought you might have looked at the BIOS setup at some time and 
changed some settings with end result being that data was turned off 
on those ports. In some setups the default behavior of these ports 
is different when "legacy" is enabled and when it is not. Actually, 
the meaning of "legacy" wrt USB port behavior seems to vary among 
the manufacturers. I found that out the hard way once when I did a 
reset to default settings on one of the machines.

On top of that, the two systems I mentioned have a wonky "GUI" BIOS 
setup program (yes, so you can use a frikkin' mouse) which seems to 
have a mind of its own. I would swear that there have been times 
when a recheck of my BIOS setup showed that a value had changed from 
my last intended setup. Whether that was a failure on my part to 
actually save the setting or error in the setup program itself is 
not clear.

Why they did this GUI thing is beyond me, but I understand from the 
SimplyNUC people that Intel has informed them that they will soon 
discontinue use of this "feature". That may mean that it was too 
buggy to bother with, or that too many curmudgeons like me whined 
about it.

I hope for you and your health that you clean up your home regularly. Two
years is nothing, however I had a situation when some fine particles get
into the usb plug of my mobile and it refused to work, because it was
covering the contact plate.

Definitely not the issue. the hovel is late 1940's construction and the
major VOC sources are 30+ years old, unless the mobo itself is toxic,
but non other of the trio has that problem.

I'm coming to the conclusion that a lot of mass produced electronic
products suffer from very poor quality soldering and this is probably
such a case.

FWIW, I experience a VOC issue in the 1990's when i was working User
support and the mob I worked for decided to go with the ACER plastic
386(?) computer into a newly buld and furnished tower building. I
quickly twigged that various computer failures were down to
'cruft' coating the various contacts and reinserting  them a few
time would fix the problem. Well before it was documented in the
science press.

We're still to experience flotsam and jetsum clogging the various
min-usbs floating around. The mobile phone spends most of it life
packed ina soft cover as it only ever travels when we go on major trips
for emergency use.
