I installed updates to my 14.04 system about once a week, including any
new kernel versions that came along (I always did "apt-get dist-
upgrade"). In other words, there wasn't really one specific kernel
version that I was using.
My dad's computer, which has pretty much the same hardware as mine (same
model motherboard and CPU, I even bought the hardware for both computers
at the same time), is still running 14.04 ("Ubuntu 14.04.5 LTS",
according to the 'lsb_release' command). The kernel version that it
currently reports (with 'uname -a') is:
Linux wkst0 3.13.0-93-generic #140-Ubuntu SMP Mon Jul 18 21:21:05 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux
As far as I can remember, his computer has been having the issue ever
since I first installed 14.04 on it: if there are no USB media present
upon shutdown, then the computer will successfully power off, but if any
USB medium is still connected, then it will reboot.
I refrained from upgrading his computer to 16.04 because under that
release, the computer will reboot, instead of powering off, even without
any USB media present. Now that I have at least a workaround for this
issue, I was considering upgrading his computer after all, but I hadn't
gotten around to it just yet.

Title:
My computer reboots instead of shutting down
Status in linux package in Ubuntu:
Incomplete
Bug description:

When I try to shutdown my computer, it seems as though it is trying to
power off, but it immediately reboots instead.
I can circumvent the problem by unbinding the EHCI drivers right
before power off. I created a systemd service to do this
automatically. First, I created a script, '/usr/local/sbin/unbind-
ehci-drivers' that the service will execute:
-----</usr/local/sbin/unbind-ehci-drivers>-----
#!/bin/sh
DRIVER_DIRECTORY='/sys/bus/pci/drivers/ehci-pci'
cd "${DRIVER_DIRECTORY}"
find -mindepth 1 -maxdepth 1 -name '*:*:*.*' -type l -printf '%f\0' | xargs
-I '{}' --null echo '{}' > unbind
-----<srevird-iche-dnibnu/nibs/lacol/rsu/>-----
Next, the '/etc/systemd/system/unbind-ehci-drivers.service' systemd
service file:
-----</etc/systemd/system/unbind-ehci-drivers.service>-----
[Unit]
Description=Unbind EHCI drivers upon system shutdown
DefaultDependencies=no
Before=halt.target
[Service]
Type=oneshot
ExecStart=/usr/local/sbin/unbind-ehci-drivers
[Install]
WantedBy=shutdown.target
-----<ecivres.srevird-iche-dnibnu/metsys/dmetsys/cte/>-----
With these files in place, the following command will enable the service:
root@localhost# systemctl enable unbind-ehci-drivers
Shutdown works now.
