I know it looks like i'm referring to literal unknown devices in device manager, but i am not. Under disk drives, there is a device called "xvd" and I have no clue what this is. If i unplug my external hard drive, and all my USB devices, it is still there. it says it's on the USB bus but it's there even when there is nothing plugged into the USB ports. It says the driver is from 2006, but this is a 2014 computer.
here is a screenshot
i haven't seen this before today, either
