Thanks for posting your question here about using the Easy Transfer Cable as a point to point USB network device, I’ll do my best to help.
I currently don’t have a cable available to test with and I didn’t find much detail available online so I’ll have to give you a better answer tomorrow when I can try it out.
In the meantime though, install the drivers if you are on XP or Vista from the following link (they’re built-in to 7 and 8):
Next we’ll look for the USB network device. If it’s visible in device manager, look at the network adapters menu. You can open it by right clicking on the network icon and then selecting “open network and sharing center” it may slightly different on your version of Windows.
Then select change adapter settings. There may be a USB network adapter listed here. (Prolific 25X10). If so right click and choose properties and then choose TCP/IP to set a static IP address that is in the same subnet as the Linux machine you want to connect to
Again, I apologize if this is inaccurate as I don’t have a cable available to test with. I’ll be able to give you a better answer tomorrow, but this is where I would start.
