Hi,
I have two smartmedia cards 16mb and 64mb. I have recently compiled the
Debian source for Kernel 2.6.0-test9.
I normally only use my 64mb card together with a usb reader. The problem I
have led me to the wrong conclusion which I reported to this group. For this
I apologise.
I have now clearly identified the problem and have repeated it and doubled
checked to ensure that this post is accurate.
The problem is;
I can mount both the 16mb and 64mb cards if I use my camera. If I use my
reader, the 16mb card mounts ok but, the 64mb card returns no media found.
When I used the 2.4.19 kernel the 64mb card worked fine with the reader. A
new addition to my setup (apart from 2.6-test) is a usb to serial adapter. I
connect all these to a usb hub running in passive mode. In case the addition
of the usb/serial adapter was not leaving enough power for the larger
capacity SM card I attached the power adapter to the hub and switched it to
'powered'. This made not difference to the problem.
my fstab entry is;
/dev/sda1 /mnt/smedia vfat rw,user,noauto 0,0
when the 64mb card is mounted in the camera fdisk -l returns;
/dev/sda1 * 1 500 63972+ 1 FAT12
Any help on this would be appreciated.

There's a typo in the above - its actually;
/dev/sda1 /mnt/smedia vfat rw,user,noauto 0 0

I wonder if you are seeing the same thing I see...
I have several different sized memory cards which I use using a usb
adaptor. The kernel (I've only tried 2.4 not 2.6) recognises the
first one fine, but refuses to update its internal knowledge of the
size of the card so if I insert a different sized one it doesn't mount
properly.
The work-around I use is to "rmmod usb-storage ; modprobe usb-storage"
whenever I change memory card - this kicks the kernel into re-reading
the size of the media (or maybe the partition table) and it all works
fine after that.
This obviously isn't ideal but I haven't found a better solution.

Nick,
Thanks for that thought. I only recently found out about that. It led me
to interpret my problem wrongly the first time.
Unfortunately this is not my problem. On a clean boot I can't mount the
64mb card in the reader, yet if I plug my camera in I can mount it there.
The 16mb card however mounts no problem in the reader.
As an alternative to the fix for the problem you see. Here is a link I
found that towards the bottom of the page has a solution. I haven't tried
it myself, but it might interest you.
http://bmiller.customer.netspace.net.au/linux/c5050.html
If ever I get my problem sorted I'll give it a try myself.

I've had this problem with 2.4 kernels as well, and use "unplug the
reader, rmmod, plug in the reader". I reported this a long time ago,
and didn't get any response IIRC.

Oh, I just realized... I should mention that I was having this problem
with CompactFlash cards of differing sizes/partitioning.

I don't have that problem, luckily, but a different one...

Sometimes kernel doesn't want to recognize the SM card in reader, and I
have to reinsert it, sometimes several times. In 2.4, one `eject
/dev/sda` fixes the problem, in 2.6 not any more. But reinserting
always helps... obviously, not ideal too, but it works for me.

I was at this again last night. I'm no further forward but, I did notice the
returned message is actually 'No medium found'. Don't no if this makes a
difference to finding a solution.

I forgot what kind of reader and what kind of cards you used.
This evening I fixed some problems with sddr09.c on SmartMedia cards
larger than 16 MB.
(patch on request, or on linux-usb)

There is a command that tells the kernel to reread:
blockdev --rereadpt /dev/foo

Thanks for getting back to me on this.
My cards are Olympus branded smartmedia cards (16mb & 64mb). The reader is
a Belkin usb reader (part # F5U141xMSD.
I have made a bit of progress. I've not changed my Linux install. Instead
today I bought myself a cheap 8 in 1 usb reader made by Typhoon. This
reads both cards just fine.
As the Belkin worked fine until I installed 2.6.0-test9 I would be
interested in applying your patch to see if it gets the Belkin working
again. Could you email me it please.
