As the title states, plugging in a MicroSDXC card directly into the MicroSDCX slot on my PC's card reader causes that drive's icon to light up, but no card is actually detected. Here's some additional info:
- Plugging a different MicroSD card into the same slot works. The card is recognized.
- Plugging in the same MicroSDXC card (the one that doesn't work) into an SD adapter and then plugging that into the normal-sized SD card (on the same reader) works!
So the only fail case is a specific card in a specific slot. Changing the card works, changing the slot works. I don't know what to make of this.
Card reader: PRO-55U
Card: SanDisk Ultra 64GB MicroSDXC
OS: Windows 7 64-bit
Note that the card reader slot is explicitly labeled "MicroSDXC", so it should be compatible
