[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!
