I do the same. In case someone wants to know how it works with an Android phone, you connect your phone to your PC over USB and then you get a notification on your phone that says something like "Charging over USB". If you tap on that, you can change the connection mode and one of the modes is "USB tethering". If you select that, your PC will have an internet connection over the USB connection to your phone. It's kinda like hotspot over USB.
