The cable arrived in a pouch with a manual and a rope.
I connected the cable directly to see, it has not worked.
With the usb often takes a driver so I got interested in the manual. I could not use the rope fault reader.
The notice provides the address of the manufacturer, I let myself be guided and a few minutes after a reboot and worked my adapter.
I confirm that it is in usb3 and to keep a gigabit connection.
After a few days it works great.
One might think that manufacturers go easier and I was disappointed with the lack of LED to indicate the status of the connection. By reflex when there is a concern, it is the first visual trick that you look. I assure you Apple products do not have either the detail.
Also, I was pleasantly surprised by extinguishing the light of the office to see a green glow on it. The adapter has a light that flashes to indicate traffic.
The adapter does not heat up and running. Not to discuss, I recommend you and give it 5 stars.
