As I have already explained that to you - in my over 15 years of Linux use, I've never seen Linux drivers are supplied on a CD. It almost always contains Windows drivers and occasionally Mac drivers.
For Linux, it is either works OOB, or requires a third party driver downloaded from the net or compileing it from the source, or does not work at all.
I saw again and again, people made a mistake trying to purchase Linux compatible hardware by the product name. The manufacturers could change any component without advanced notices. The only way to know for sure is to look for the model number of chipsets it contains.
It is also advisable to go for a online shop which offers you an easy return. Sometimes people who are selling the item has no idea what they are selling. For this reason I seldom use evileBay. That is my last resort when I cannot find what I want at Amazon with a reasonable price tag.
