I'm not getting these messages, but I did just now run 
into a weird vfat over usb_storage problem.

Camera is an Olympus C-3020, kernel is 2.6.0-test9-mm3, 
the usual configs to allow access to this camera.

The card was about full, so I turned it on and mounted it 
as usual.  Acessing it with filerunner, I started at the 
top of the list, deleting pix I had already downloaded to 
/usr/pix.  I deleted about 15 in the first batch, then 
around 10 in the next batch, and about 20 in the third batch.
Hi-lighting about another 20 and hitting delete got me a 
read-only file system error on the last one, but it did 
delete the rest of them.  I had about 60 left to delete, 
but had to umount the camera and turn it off, turn it back 
on about 10 secs later, and remount the camera (same device 
BTW, thanks guys) about 5 or 6 times before I was able to 
get that 64meg card all cleaned out.

And once again, I have NDI if its buggy software in the 
camera, or a usb_storage problem.

Here is one such section of the messages log:

The "assigned address" was being incremented per disconnect.
And, /dev/camera is a link to /dev/sda1.  Is this wrong?
However attempting to mount it useing /dev/sg2 fails, not 
a valid block device.

Comments?  Screwed up kernel .config? Is mount "-t vfat" the 
correct filesystem?

Thanks.
