RE: USB SanDisk SmartMedia - some results.

I'm a little confused.  Are you working with SanDisk on this?
Also, have you tried to use the usb-storage driver with this
device?  Matt Dharm has been working with SanDisk on
CompactFlash, but I don't know about SmartMedia.

Phil Davis ([e-mail]) reported on 2000-apr-11 on
the linux-usb mailing list:
"I have got the Fujifilm SM-R1 SmartMedia reader "working" sometimes."
so I think that the usb-storage driver is the right one to use,
although it may need some tweaking.

These are device descriptor data for devices 1 and 2 as listed
below in ASCII in /proc/bus/usb/devices , uh, I mean in /mnt/usb/devices .

Try the usb-storage driver.  Check the linux-usb email archives
for other SmartMedia attempts and results.
