Sorry for the looong delay regarding that card. I found what the problem
with those 4GB Transcend cards is, but I still didn't add the necessary
code to make the card work after USB (aka tell the user that he has to
pull & re-plug it - it's a card firmware problem, nothing we can solve
for real).

Other than that, MMCs just work fine in my Ondio SP and FM, as well as
pixelma's Ondio FM. 128MB (CnMemory), 256MB (Transcend), 1GB
(Transcend), 2GB (Magu), 4GB (A-Data), 4GB (Kingston) all work as
expected. They do so in any release of Rockbox for Ondio, as well as
current SVN.

The 4GB Transcend also works since SVN r18515 (release 3.0 or maybe
3.0.1), except when plugged at boot, or directly after USB.

So there are some questions to you two:

- What card type/ brand are you having problems with?
- Does the card work when hot plugged?
- What's your hardware mask? System->Debug->View HW Info, Mask: __
- Does System->Debug->View disk info find the MMC (when hot plugged)?
   You have to press RIGHT so it shows [MMC 1] at the top - [MMC 0] is
   the built-in storage. If it does show real values, please include them


Regards, Jens
