[Pkg-phototools-devel] Bug#509293: libgphoto2-2: udev rules broken - use "usb_device" rather than "usb|usb_device"

Package: libgphoto2-2
Version: 2.4.1-3
Severity: important

Incorrect udev rules in the latest libgphoto2-2 package are not creating USB
device files in the plugdev group.  That means I can run gphoto2 as root, but
not as a normal user.

/etc/udev/rules.d/025_libgphoto2.rules includes this skip rule:

	SUBSYSTEM!="usb|usb_device", GOTO="libgphoto2_rules_end"

The pipe is not documented to work in the udev manpage, and I think this is the
problem.  When I change the line to:

	SUBSYSTEM!="usb_device", GOTO="libgphoto2_rules_end"

I can access the camera as a normal user.

I have CONFIG_USB_DEVICE_CLASS=y in my kernel config.  (I looked because of bug
427963.)  I did comment out the /etc/fstab rule to automatically mount usbdevfs
because I'm a USB developer and I need to be able to remove the USB core module.
