“1 Preliminary Note: The smartphone I use in this tutorial is
the HTC Desire A8181, the screenshots originate from the same
model. The guide should work for similar smartphones with Android
installed. No extra software is needed to enable USB tethering on
Linux Mint.“2 Setting Up USB Tethering On Your Phone: To access the
Internet on your computer using your phone’s network, first make
sure the smartphone itself has a connection to a mobile network. If
it does not, enable that first. If your phone is able to connect to
a mobile network, go to Menu > Settings > Wireless &
networks and make sure that Mobile network is turned on.“Having done that, plug your phone into your computer via USB.
If your phone was turned on while doing so, the following screen
will appear.”
