To Install USB Driver for Windows
Note
It is recommended that you use a USB 2.0 port when tethering, but if
your computer only has USB 3.0 ports, try to update the USB 3.0 host
controller driver. If your computer has a mix of USB 2.0 and USB 3.0
ports, you can identify USB 3.0 ports by color. On many newer systems, a
USB 3.0 port may be identified by having blue plastic components.
