|Please note that your keyboard and mouse need to be connected directly to a USB port directly on the motherboard, preferably one of the rear ports. Nearly anything else can be on a hub.A USB hub may not be fully functional until Windows fully loads so in order to enter Windows password, enter BIOS set up, Choose advanced boot options, and more, the keyboard especially needs to be directly plugged in.|
Suggestion: If this s a desktop, pop open the side of the unit and look for a onboard USB connector or two on the motherboard, if they are there and open, you can get a front or rear expansion port for your machine that will plug into these, they come in 2 and 4 port varieties with two per motherboard connector. You will probably need to be able to identify whether they are USB2.0 or USB3.0 ports but you can Google for pictures if needed. Some have built in hubs which may even contain other ports but I generally prefer the non hub direct variety (which could be used for keyboard where the hub variety cannot).
You have to be a little bit crazy to keep you from going insane.
