Cellular USB Tethering
usb_moded is a daemon that activates a USB (Universal Serial Bus) profile based on the USB cable connection status that it tracks.
It uses a D-Bus system bus for all the system wide communications. Among other functionality usb_moded can set up USB tethering, ie: it can share the data connection of the device with another device.A typical case of this is a laptop using a mobile phone for connecting to the Internet. When a cellular network is used to access the Internet, oFono is used to check if the device is roaming, and if so, if roaming is allowed. (Roaming means using the cellular connection outside the home subscription network.)
