Just had an issue since I formatted my PC.... Never previously had an issue with it, but my PC now has all USB ports operating at USB 1.1 speeds. I've installed all drivers for the motherboard and nothing is shown as missing drivers, but every time I plug in a USB 2.0 device, I get a message saying it can perform faster if put into a USB 2.0 port. Any ideas?

maybe you have disabled the USB 2.0 controller in the BIOS of your motherboard.
Go in the BIOS:
Press del, f2 or f1, sometimes f12 at startup until you get the BIOS Screen.
Switch to advanced and look for USB Controller or something else. Look if your 2.0 controller is up and running. If not, enable it. So that`s all.
Then you can use your faster connection, again ;)
