Not sure if you really meant that your computer does not have an ethernet port so you had to buy an ethernet-to-USB adapter.
If so, you must have a pretty old laptop.
Eitherway, even if you use an USB to Ethernet adapter, you still need to use some type of port redirector on your computer.
Aquanotes will not let you get info from the USB port so you need to find a way to fool Aquanotes into thinking that a USB port is an ethernet port. For this, you would need some type of port redirector. A program that can emmulate an ethernet connection and route it to your USB port for communication.
Not an easy installation if you ask me but it can be done.
