I have bought a new Logitech G510 keyboard and G500 mouse for which I have installed the Logitech Gaming Software 7.00.291 which I used most of the time while gaming on this machine. But the problem is whenever my computer goes to sleep mode, Coming back from the sleep mode does not show my mouse or keyboard. I have to reboot my machine, As nothing works without rebooting my machine. Please help! I am running a Windows 7 on this machine.
