Not recognizing USB

[cover]

I have a new 8.1 machine that isn't recognizing USB port items when plugged in. Is there something I can do to correct that? I have a Windows 7 machine right next to it and the same item is picked up just fine when plugged into a USB port. Thanks for any ideas.

Is it ALL usb? Have you checked usb / mouse keyboard? Or is it just usb flash drives and disk? Have you installed the chipset drivers for your machine? Go to the vendor support site for your machine.

You should also add your system specs to your profile if you need further help
