I've a smartmedia reader (HH501 (0x502 and 0x503)/Foxconn Hai (0x489)) but
without any support. From the windows drivers, i've extract the firmware. The
command is send directly to the ezusb external bus, so i can't know the exact
list of commands. I've build some tools to send command, and try to guess it
from the windows drivers. I can detect if a card is inserted, read the memory,
read the mapping table (with some problem). All theses operations were made
wihout any documentation except for the ezusb chip, so i think it's buggy.
My tools works in userland. I dump the all memory into a file, then i mount the
file with the loopback interface. It's not perfect but it work for my 8Mb
memory (not with the 64Mb :( ).
Each command is 8 bytes lenght, and is pretty close to the protocol use in the
file sddr09.c. If i want to write a kernel driver, i need to hack it, or to
create a new file with many same portion code.
I think a common API can be pretty useful.
