It works, but uses illegal MAC addresses
on August 14, 2013
I purchased the Cable Matters USB 3.0 Gigabit Ethernet adapter for a 2012 MacBook Pro Retina model. Overall it's fine: It's cheap, it works, it's reasonably quick. I do not like having to install a driver (and reboot) but it's acceptable. I recommend a web search for ASIX AX88179 drivers to locate the latest version.
One tip for Mac users: After installation, go to System Preferences -> Network -> Set Service Order (in the gear drop-down) and prioritize the USB 3.0 adapter over your Wi-Fi network. By default it will use Wi-Fi if both are connected, and this is probably not what you want.
But I uncovered a serious technical issue with the device: Cable Matters illegally programs these devices with an Ethernet OUI of 00:00:00. This belongs to Xerox and it is NOT kosher to do this. It is unlikely to cause any issue for a user, but I am disappointed by this kind of corner-cutting. It makes me worry about the OTHER corners the company may have cut, and leads me to no recommend this device.
I don't have a better suggestion, but I wouldn't buy this adapter again.
Note: I posted a full review of this device on my blog. Search for Stephen Foskett Cable Matters USB Ethernet Review and you'll find it.
