The reason you're getting that message is because you're using an unlicenced accessory made and sold without permission by Apple. There's no guarantee you'll ever be able to get that card reader to work as it does not have the Apple authentication chip in the Lightning connector.
Having the unsupported device message show up is the chance you have to take when buying cheap unlicenced accessories. There are licenced accessories by third party manufacturers that are cheaper than official Apple accessories but not as cheap as the unlicenced accessories.

Apple started using the authentication chip in accessories as a way of slowing down the flood of counterfeit Apple accessories on the market.
