Hello,
I want to access a SmartMedia card on a USB adapter with JFFS2 filesystem.
The USB reader is recognized fine and seems to detect the card correctly.
My question is how can I direct the MTD subsystem to use the USB adapter?
Is this supported?
Thanks,
Sid

I suspect that you don't. Although SmartMedia is basically just NAND
flash, the USB 'cardreader' will probably be hiding all that from you
and presenting itself USB mass storage device. Turn on CONFIG_SCSI and
CONFIG_USB_STORAGE.

It depends on the card reader.
Some of them look like a USB mass storage device (which would not work with
mtd as NAND). Some send read/write/erase commands over the USB link - these
could be made visible as NAND under mtd.
