Comment 43 for bug 67532

Dear all,

I am working with Aiptek mini Pencam 1.3, Vendor ID 04fc; Product ID: 504a. Then i did the fix for both bug 64146, bug 67532 and bug 91250
add a line: SYSFS{idVendor}=="04fc", SYSFS{idProduct}=="504a", MODE="0660", GROUP="plugdev"
and
changing the BUS!="usb*"... line to SUBSYSTEM!="usb_device"...
or add a line :
ENV{INTERFACE}=="6/1/1", MODE="0660", GROUP="plugdev"

But nothing can help! I still got the following error when trying to
access the camera to get info or download picture (by gphoto 2):

 gphoto2 --camera "Aiptek Pencam" --port "usb:001,016" --list-files

*** Error ***
