Picture of other side PCB: The biggest difference is this: However for clients it is written that they are supposed to accept a wide range of voltages I forget how high and not blow up. When I ran a TCP throughput test with iperf , they both performed well. One thing that surprised me is that the cheap adapter has a functioning blue activity LED, that glows through the enclosure.

However for clients it is written that they are supposed to accept a wide range of voltages I forget how high and not blow ueb. Taking apart a very cheap USB to Ethernet adapter and pondering on the parts found inside. But the guys at ASIX, who know their own software and hardware inside and out can easily build-in some functionality to test if there is a genuine ASIX chip fitted.
