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?

I'm unsure about the older scheme (assigned by MMCA), but ever since
MMC is now JEDEC-controlled, the IDs have changed. Sandisk's new id
will be 0x45, and Toshiba I guess will be 0x11.
