ive found it rather annoying that when my computer goes to sleep and then wakes up all my logitech devices are quite useless as the gaming software doesnt reinitialise them so heres the fix
This works for Windows 7 x64 atleast.. not sure about other OS's
Create a "Restart Logitech.Bat"
insdie that file you need to put
@echo off
echo Killing processes...
taskkill /f /t /im LCore.exe
echo Restarting processes...
start "" "C:\Program Files\Logitech Gaming Software\LCore.exe" /minimized
echo All done!
you may need to change the paths
then start Task Scheduler and make a new task
General Tab i only have run when user is logged on selected
Triggers this is the tricky one
create a new trigger.. select On Event then Select Custom
New Event Filter, i selected all the Checkbox's you prolly dont need them all but i just wanted the fix done fast and couldnt be botherd to work out which event type it is
then Select By Source, pull down the menu and find and select Power-Troubleshooter
in event Id type 1 then hit ok till your back at the Triggers Window
select Actions and then start a program and point to the .Bat we made earlier
move over to Settings
i have everything selected here except "if task is not Scheduled to run delete...." we dont want that one
as long as ya could find and do everything correctly.. hit sleep on the start menu.. let it shut down and start it back up again.. a few moments after the system has woken up it should kill the old gaming software and restart it.. you'l see your devices transfering profiles and away she goes 
good luck n have fun i hope this helps some peops
