Unfortunately, installing drivers in Win7 not work for me on my T420. Accordingly, I can not use a USB 3.0 here. The individual driver files are available from the manufacturer as far as I do not see available for download. So to sum it in my case under Windows7 useless. Since I used Windows only for individual special tasks and otherwise only the much more comfortable Linux, can I use the adapter: Ubuntu runs without further action .... so goes the operating system.
