My keyboard won't normally type when I start it up. I have to right click my computer, select manage, device manager, human interface devices, then uninstall my first USB human interface device (keyboard) that always has a yellow exclamation point on it, then restart my computer when it prompts me to. After this, I can type when I log back in, and the problem doesn't start up again until the next time I turn the computer on again. this is driving me NUTS, please help me figure out the problem. I have tried other keyboards, same problem, and I don't know if this is important, but my Logitech keyboard has some extra buttons on it, like ones that open calculator and search menu, and those DO work, but all the normal letter keys like L don't.
