Thanks

Try this.
It will disable my usb keyboard. May work for your devices.

Get your usb id.....

xinput

Then use...

xinput --disable x

...where x is your usb id.

To enable....

xinput --enable x

Been playing around with this and came up with a toggle on/off script.
The script will toggle my "Nostromo SpeedPad2" gaming keyboard on/off.
Could adapt it for your device.

eg this is my xinput...

glen@Raring:~$ xinput --list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ DEXIN Tt eSPORTS BLACK Gaming mouse     	id=11	[slave  pointer  (2)]
⎜   ↳ DEXIN Tt eSPORTS BLACK Gaming mouse     	id=12	[slave  pointer  (2)]
⎜   ↳ Honey Bee  Nostromo SpeedPad2           	id=9	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Logitech Logitech USB Headset           	id=10	[slave  keyboard (3)]
    ↳ Ideazon Zboard                          	id=14	[slave  keyboard (3)]
    ↳ Ideazon Zboard                          	id=13	[slave  keyboard (3)]
    ↳ Honey Bee  Nostromo SpeedPad2           	id=8	[slave  keyboard (3)]

....and from that output derived this toggle script...

#!/bin/bash

# Script to toggle a usb device on/off
# This works to disable my Nostromo SpeedPad2 that I only use for gaming.
# Need to adapt deviceid variable to use your device from the output of "xinput --list"

deviceid=$(xinput --list | awk '/Virtual core keyboard/{y=1;next}y' | grep -m1 "Nostromo" | awk '{print $6}' | tr -d 'id=')
devicestate=$(xinput --list-props $deviceid | awk '/Device Enabled/ {print $4}') # 0=disabled 1=enabled
devicename=$(xinput --list --name-only $deviceid)

if [ $devicestate = 0 ]; then
	xinput --enable $deviceid
	notify-send -i keyboard "Enabled" "$devicename"
else
	xinput --disable $deviceid
	notify-send -i keyboard "Disabled" "$devicename"
fi

If you need help to make the script work for your device
post the results from...

xinput --list

Oh well, I thought they would show in xinput,
and the script works so nicely with my gaming pad.
