OK, I'm at my wits end... after three days of Googling, searching these boards and close to pulling out all my hair, I hereby admit defeat. Here's the lowdown...
Task
Getting my Panasonic Lumix DMC-LC20 digital still camera to be mounted as a vfat partition. This is done on a 2.6.1 kernel with hotplug enabled.
What I've done
Created the relevant entry in /etc/fstab.
Ensured that there's kernel support for relevant modules.
Attempt to mount the device.
End results
Code:
mount: No medium found
And yes, there is actually an MMC card inside the camera, so it's not forgetfulness on my part.
Other worthy mentions
Yes, I've tried to flush the device buffers (blockdev --flushbufs /dev/sda1).
Yes, I've tried to boot with the camera on.
Yes, I've tried adding usb-storage to /etc/hotplug/blacklist.
...but it's all in vain
Now, I hereby seek help from those more knowledgable and those who have done something similar on a 2.6.1 kernel. I have no such problems with this camera on the 2.4.x kernels, so it's definitely either one of two things:
1) I'm missing something with my kernel config.
2) There's something wrong with the way 2.6.1 handles my camera.
The strange thing however, is that the camera is detected... But why doesn't it see the partition
I always read your posts for valuable information. You're always helping others, so let me at least take a stab in the dark. What have you got to lose? My information may not apply, though, as I use 2.4.23 and not 2.6.1.
When I want to mount my camera I issue
$ mount /mnt/camera (staying away from root login)
and then view and copy the photos/mpegs using Konqueror. I use this mount point for a Sony DSC-F707 camera, an OnData USB flash disk, and a Toshiba USB hard drive. The device doesn't matter. I plug any of them into a front USB port (or rear by the p/s if I want USB 2.0) and just issue the same command.
I built the support into the kernel rather than using modules, so I won't give you lsmod output. Nothing there but video and sound.
More info than you need, but since you're better at reading this than me, here goes...
and I don't mind looking like a fool for not knowing. Anything you learn from reading my entries might be the only help I could give you.

Sorry but I didn't know how to output dmesg as you did, and I've probably been no help. I subscribed to your thread and had to try something to help you. I'll go to bed now. Hope something in here is more help than entropy :}
Thank you for your input. However, like I said in the post, I don't have any problems with the camera on 2.4.x kernels. I think it's definitely something on the kernel side of things. I've noticed someone facing similar problems on the lkml.
Unfortunately, the thread evolved into a more technical (asm, c codes) discussion, and due to my illiteracy in those programming languages, I guess all I can do is wait patiently
However, I highly appreciate your effort and I know that it'll definitely help people with problems on 2.4.x kernels.
I faced the same problem. My camera is a Nikon Coolpix 2000 and it worked perfectly under 2.4.x but not under 2.6.x (I've tried from 2.6.0-test6 from 2.6.1).
You may find some "emergency patches". I have'nt tried any of them by myself.
However, I've been able to read the photos using PTP protocol (instead of Mass Storage) using gPhoto2. It's been a little hard to configure and it doesn't work 100% for me, but it does the trick until new usb drivers come.
I read that particular thread as well, but never had the balls to patch my kernel. But today, I finally gathered enough courage and gave it a try... And guess what, it works!
I'm a hapy man. Thanks for the pointer.
And, in the spirit of giving back to the community, I'll just post a mini-HOWTO here on the process.
How to patch your 2.6.1 kernel to get your Lumix (and probably other brands/models as well) Camera Working
Note: In future releases of the 2.6 kernel series, this problem might have been fixed, so this particular mini-HOWTO only applies to 2.6.1 and 2.6.0 kernels only.
Step 1: Create the patchfile
Fire up your favourite editor and create a patchfile containing these lines:
Code:
--- sd.c Mon Nov 10 10:26:50 2003
+++ sd.c Sun Jan 4 15:30:59 2004
@@ -606,9 +606,13 @@
* by sd_spinup_disk() from sd_revalidate_disk(), which happens whenever
* sd_revalidate() is called.
*/
+#if 0
retval = -ENODEV;
if (scsi_block_when_processing_errors(sdp))
retval = scsi_ioctl(sdp, SCSI_IOCTL_TEST_UNIT_READY, NULL);
+#else
+ retval = 0;
+#endif
/*
* Unable to test, unit probably not ready. This usually
Save the file at [your kernel source dir]/drivers/scsi/
Step 2: Backup your original sd.c file
Go to the location where you saved the patchfile, and backup the unmodified sd.c file first. You might need to revert to the original file when you want to patch your kernel for upgrading in the future.
Code:
cp sd.c sd.original
Step 3: Patch the file
Just run this command at a prompt, replacing patchfile with whatever filename you used in Step 1: patch -l -p0 <patchfile
That's it! Now all you got to do is to recompile your kernel to mount your camera without problems. Hope this will help anyone facing the same problem
Notes: Credit goes to Alan Stern from the linux-usb-devel team for the patch.
Well, finally I dared to try... and I must say that everything works fine now (except that supermount doesn't detect when the device is unplugged. I'll try the latest version and we'll see...).
Bye
SnOp
P.D.: Does anyone knows if this problem has been fixed in 2.6.0 ?
I'm sorry. What I want to know if the problem persists in 2.6.2 (I'm already using 2.6.1).
Edit:
What prevented me to try 2.6.2 was the fact that no supermount patch was already available...until now. So I tried 2.6.2 and I've found that my camera doesn't work as well as it doen't work with 2.6.0/1.
These are the bad news. The good news are that the patch mentioned above can be applied and works for me.
