I get "No medium found" when I try to mount the SD card inside my digital
camera (Panasonic DMC-LC33.) It works fine in 2.4.18 that comes with Debian,
but I get the above message in 2.6.0 (and couple of releases before it - it
is a fairly new camera, ~2 months old.)

Any ideas how to debug it?


When plugged in:

kernel: hub 2-2:1.0: new USB device on port 4, assigned address 3
kernel: Initializing USB Mass Storage driver...
kernel: scsi1 : SCSI emulation for USB Mass Storage devices

scsi.agent[22366]: disk at /devices/pci0000:00/0000:00:1f.4/

When I try to mount it, mount refuses, but there are no log messages:

jeff:~# mount /dev/sda1 /mnt/camera/
mount: No medium found

And when I shut the camera off, I get:

kernel: usb 2-2.4: USB disconnect, address 3

The modules:

jeff:~# lsmod
