Your computer has ports that are older technology than the thumbdrive that you purchased. While new usb standards require backward compatibility, the speeds are limited to the version of usb that accesses the drive. What that means is that two ports of your computer will be limited to usb2.0 speeds and one will be limited to usb3.0 speeds. Your computer doesn't support usb3.1. The drive will work, but not at the 3.1 speeds. There is no getting around the limitations of the hardware except by purchasing a computer with those new standards.
