Maybe, if SDXD is formated to FAT 32 (which is not possible in Win, I guess, without using non-M$ tools.), it might work.
I have a device which officialy supports only SD (up to 4 GB). I may use in it SDHC up to 32 GB. And maybe even SDXD, I didn't try.
So, the conclusion is. Someone has to try it in M92 (and format the card to FAT32 first).
