This option supports devices conforming to the Communication Device

implement in device firmware. The CDC EEM specifications are available
from <http://www.usb.org/>.
This driver creates an interface named "ethX", where X depends on
what other networking devices you have in use. However, if the
IEEE 802 "local assignment" bit is set in the address, a "usbX"
name is used instead.
