Corsair RGBK95 and M65 USB Issue

Hey guys I just got this new mouse and keyboard combo and I love them so far however more often than not when I start my PC they two devices don't register and I have to unplug and re plug them in to get them to work, It can get really annoying considering they are plugged into the back of the PC anyone else have a similar issue/solution thanks!

Had same problem and fixed with firmware update and also plugged the mouse into a PS/2 adapter and skipped the USB input. Dont know which fixed it.
