I have a mid-2014 13" MacBook Pro , and I'm trying to get my new Ethernet to USB adapter from Radioshack. Nothing shows up in the Networks pane of System preferences, and when I turn off wifi I can no longer connect to the internet. It came with drivers, and I installed that package and then restarted but nothing shows up for this adapter. Is there a certain order I should be plugging the various cables in? Is it possible the problem is with the Ethernet cable which is also new? I'm trying to figure out how I can get this device working. Here is a picture of how it shows up in System Information: (It says USB 2.0, but the 12mbps speed and the fact that the manual says it is USB 1.1 say otherwise). Any ideas on how to make this work?
