I'm curious. Neither the manfid nor the oemid fields of either card
match what I have seen on SD cards, I would expect them to be
Sandisk: manfid 0x000003, oemid 0x5344
Toshiba: manfid 0x000002, oemid 0x544d
I have not actually seen any Toshiba SD cards, but I assume that they
use the same controllers as Kingston.
Does anyone know if the IDs have any correlation between MMC and SD
controllers?
