It looks like either the driver for the usb-eth adaptor is not installed, the adapter is bad, or the cable is wrong/bad. If it was correctly connected and installed, there would be an adapter listed that has an IP address of 169.254.xxx.xxx.
Just a shot in the dark but it’s possible that the adapter you are using is a 10/100 adapter and my guess is that the Ruida controller has a 10/100 adapter, not a gigabit adapter. This means that unless you are using what’s called a crossover ethernet cable, it won’t link between the two machines. If either or both have 10/100/1000 (gigabit) network adapters, then it would link with a standard ethernet cable. Most usb-eth adapters have two lights built into the network jack. If neither of them are on, then you have a physical connection problem that needs to be addressed before continuing.
