I was really excited when I got them for a small project I'm building, but when I plug them into my Mac the computer recognizes them not it in any USB port. All my other boards show up in the USB tree under System Report USB. I'm testing 4 other cables but it's definitely not the right cable, the board seems defective :(. Non-refundable as the shipping cost is about the same as buying a new one. Update: I'd like to update the review to 4 stars because the seller has great customer service and they kindly contacted me and sent me a replacement for the faulty card.The new card works and I know I'm developing my project.Thanks for the good customer service.
