PCMCIA controller to CF card.

[Shishir]

Dear all,

I have a board which provides a PC Card controller to a Compact
Flash (CF) slot and I need to write a driver for this.

A similar situation occurs when an ATA (IDE) disk comes with a
USB interface. There a USB mass generic driver just works with
any such device. This is possible due probably to the USB spec.
identification of storage class device.

My question is this: can I expect a similar behaviour with CF slots
have PC Card or ATA interfaces? It seems that this is the case
but I am not sure whether it's a specification guaranteed or just
a common behaviour. (I do not have option to check this in my
case and knowing this I can go on and do other tasks.)

If above doesn't work, can somebody please give opinions on
what to choose for the driver : ATA interface or PC Card?

Thank you.

Best regards,
Shishir.
