Even worse, the windows drivers know they're knock offs and let you use them for a bit and then error out. It's the perfect lesson. They give you that high of "yes, I got one over on the big guys, we're cruising now" and then "I don't know boss it's just all of a sudden not working anymore. Yes I know we're in a production crunch. Yes we should've just bought the real one". On Linux though, no issues for me
