There is a driver CD case, but which we did not need. Our Windows 7 on the Dell has the automatically detected. Just plug it in and let make the PC. Whether that goes on all systems without driver CD, I do not know. We have all been playing Windows 7 and since this works excellent.
The adapter should also be compatible with Windows 8, Mac and Linux, which I gather the imprint on the packaging.
Class thing. So far I am very satisfied with all UGREEN products. The quality was always very good and it is also here.
