[Pkg-phototools-devel] Bug#479135: 479135: Reproduced, have some ideas

[Alexander E. Patrakov]

I can reproduce this bug with my Panasonic Lumix DMC-FS3 camera. Some 
observations:

1) Udev is irrelevant, HAL is the curlpit (somehow upsets the camera). If I 
stop hal, I can mount the camera manually. If HAL is running, the kernel 
doesn't create /dev/sdb1.

2) There is some confusion (same USB device ID, completely different cameras) 
of my DMC-FS3 camera and the DMC-FZ10/FZ20 models. For some reason, FZ10/FZ20 
needs a custom libgphoto2 driver (that can talk to DMC-FS3 in PTP mode just 
fine), while DMC-FS3 is well supported as a USB PTP Class camera.

3) If I remove the following part 
of /usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi

   <match key="usb.vendor_id" int="1242">
    <match key="usb.product_id" int="9074">
     <merge key="info.category" type="string">camera</merge>
     <append key="info.capabilities" type="strlist">camera</append>
     <merge key="camera.access_method" type="string">ptp</merge>
     <merge key="camera.libgphoto2.name" type="string">Panasonic 
DMC-LC1</merge>
     <merge key="camera.libgphoto2.support" type="bool">true</merge>
    </match>
   </match>

and all other snippets about usb.product_id 9074 (found out by "echo $(( 
0x2372 ))", where 2372 is from lsusb output), my camera starts working as USB 
storage. Can anyone confirm that all cameras with USB ID 04da:2372 are in 
fact mass storage devices and thus should not be supported by libgphoto2?

Here is my camera in PTP mode (PTP and USB storage modes are selectable via 
buttons on the camera):
