Intel SD Card Reader

[ammulder]

I've got a NUC with a built-in SD card reader. I put a card in, but I don't see it mounted, so it doesn't seem to work out of the box. I saw a thread on making a kext for a USB reader, but this doesn't seem like a USB one to me (at least, I don't see anything for it under XHC).

In IORegistryExplorer, I see:
LPCB@1F = 8086:9d48 (seems like an I/O interface reported to be used for SD cards?)
PSDC@1E,6 = 8086:9d2d (seems like the SD card reader itself?)

Any suggestions would be appreciated.

Most PCIe SD card readers not supported -- no drivers...

Note: LPCB is the Intel chipset LPC device (see chipset data sheet for more info).

You should check in Windows to determine which device is the card reader and how it is connected.
