Upon resuming computer work after my desktop has went into sleep mode the mouse and keyboard will emit light but will not work, and i repeatedly here the noises that are made when USB devices are inserted and removed, after a while sometimes they will begin to work otherwise i have to go to the back of my computer which is quite difficult because i cant see where i am plugging into and unplug and replug the mouse and keyboard which is a very tedious task and i would really like to find a way to stop that from happening, so if you have any answers please tell me. @ Thanks
