USB Tethering
You can attach (tether) the mobile hotspot directly to a single device to charge the
mobile hotspot or to allow the attached device to use the mobile hotspot’s data
connection instead of connecting via Wi-Fi.
• For the attached device to use the data connection, enable USB Tethering. To only
charge the device without routing the traffic, disable USB Tethering.
• If your device is a computer running Windows XP, the first time you tether it you
must load device drivers from the mobile hotspot.
