Why are you running such an old kernel with the latest udev?

The usb device nodes have changed to real nodes in the meantime and
the proc interface is deprecated. GROUP assignments never worked
for proc nodes and udev never cared about his. Something else may have
changed the ownership in the past which stopped doing it, but it's not
udev.

It's not likely that someone here has an idea how to help with such
a setup.
