On MicroSD Card Problems
Furthermore, the manufacturer's ID is 0×41 (ASCII 'A'), which I don't recognize (supposedly the SD group assigns all the MIDs but I don't see a public list of them anywhere). The OEMID is also 0×3432, which is suspiciously ASCII '42â€² (one more than the hex value for the manufacturer ID). These hex/ascii confusions are possible signs that someone who didn't appreciate the meaning of these fields was running a ghost shift making these cards.
Armed with this evidence, we confronted Kingston -- both the distributor in China as well as the US sales rep. First, we wanted to know if these were real cards, and second, if they were real cards, why were the serialization codes irregular? After some time, the Kingston guys came back to us and swore these cards were authentic, not fakes, but at least they reversed their position on not offering an exchange on the cards -- they took back the programmed cards and exchanged them for new ones, no further questions asked.
However, they never answered as to why their card ID numbers were irregular. While I know chumby is a small fry customer compared to the Nokias of the world, I think it's still important that they answer basic questions about their quality control process even to the small fry. I had an issue once with an old version of a Quintic part being accidentally shipped to me, and once I could prove the issue to them, I received world-class customer service from Quintic, a full explanation, and an immediate and full exchange of the parts at their cost. That was exemplary service, and I commend and strongly recommend Quintic for it. Kingston, on the other hand, did not set an example to follow.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
