Is it possible to install some kind of USB to Ethernet adapter to join the modem to an Ethernet-only device?
USB to Ethernet adapter cables exist that join a USB port to an RJ-45 Ethernet port. These network cables are designed to connect two computers. For these cables to work, special network drivers must exist on the USB device to manage the USB end of the connection. On a computer, these drivers can be installed through its network operating system. Such drivers cannot be installed on USB modems as these devices lack general-purpose computing capability.
