[By the way - until a fix reaches everybody, here is a script that I found
online and modified to fit my system...
The commented-out for statement is as the script was found.]
#!/bin/bash
if [[ $EUID != 0 ]] ; then
echo This must be run as root!
exit 1
fi
#for xhci in /sys/bus/pci/drivers/?hci_hcd ; do
for xhci in /sys/bus/pci/drivers/?hci-pci ; do
if ! cd $xhci ; then
echo Weird error. Failed to change directory to $xhci
exit 1
fi
echo Resetting devices from $xhci...
for i in ????:??:??.? ; do
if [ $i == "????:??:??.?" ]; then
echo “ignoring”
continue
fi
echo “Device $xhci:$i”
echo -n "$i" > unbind
echo -n "$i" > bind
done
done
-------------------------------
I also found PointerKeys very useful before I found the above script,
as one of the disconnected devices was my mouse!
http://en.wikipedia.org/wiki/Mouse_keys
http://en.linuxreviews.org/HOWTO_use_the_numeric_keyboard_keys_as_mouse_in_XOrg
)
setxkbmap -option keypad:pointerkeys
or, to have it always available:
Make a file “ /etc/X11/xorg.conf.d/20-pointerkeys.conf” (need sudo to create
file)
(now: “/usr/share/X11/xorg.conf.d/..”)
Put in it:
“
Section "InputClass"
Identifier "PointerKeys"
MatchIsKeyboard "yes"
Option "XkbOptions" "keypad:pointerkeys"
EndSection
“
[de]activate with Shift-Numlock.
Hope this helps someone!

Title:
specific USB devices disconnect and don't reconnect
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Yakkety:
In Progress
Bug description:
2 USB ports randomly disconnect and don't reconnect (it's always the
same two), and in dmesg all I get is
"
[ 1276.916458] ohci-pci 0000:00:12.0: HcDoneHead not written back; disabled
[ 1276.916467] ohci-pci 0000:00:12.0: HC died; cleaning up
[ 1276.916553] usb 3-1: USB disconnect, device number 2
[ 1277.017302] usb 3-2: USB disconnect, device number 3
"
This only started happening when Yakkety went to the 4.8 branch, with 4.7
branch this doesn't occur, hence the bug report since it's unlikely that a
hardware failure will only stick to one OS and one branch of the kernel for
that OS. (these USB ports don't randomly die on Windows or BSD, I've tested
that in the past couple of days)
