Attached.

Maybe, it makes sense to have different names for the cameras: "Disney 
pix micro 352x288" and "Disney pix micro 640x480".

I've made a set of experiments. First, in camlibs/digigr8/library.c, I 
changed
{"Disney pix micro",GP_DRIVER_STATUS_EXPERIMENTAL, 0x2770, 0x9050}
to
{"Disney pix micro",GP_DRIVER_STATUS_PRODUCTION, 0x2770, 0x9052}

$gphoto2 -a
Abilities for camera             : Disney pix micro VGA
Serial port support              : no
USB support                      : yes
Capture choices                  :
                                  : Preview
Configuration support            : no
Delete selected files on camera  : no
Delete all files on camera       : yes
File preview (thumbnail) support : yes
File upload support              : no

Then I made 3 shots using the button on the camera:

$gphoto2 -L
There are 3 files in folder '/'.
#1     pict001.ppm
#2     pict002.ppm
#3     pict003.ppm

$gphoto2 -D
*** Error ***

$gphoto2 -d 2
*** Error ***

$gphoto2 --capture-image
*** Error ***
This camera can not capture.
ERROR: Could not capture.

$gphoto2 --capture-preview
Saving file as digi_cap.ppm
$gphoto2 -L
There is no file in folder '/'.

I could not find any "digi_cap.ppm" file after the capture-preview 
command. And the camera lost all the images.

I will try.

Yes, I think so. Mine behaves as you describe in README.9050. (I have 
not tried sq_raw_converter yet.)
