just becuase it says it’s supported doesn’t mean it is. Some manufactures will use the same chip but the PCIID differs. sometimes if you know what you are doing you can add the ID recompile the driver and it will work, if the difference is significant enough more driver hacks are needed, easier to just get a card that is actually supported and not spend days trying to get the thing to work.
