OK, as it turns out I was half wrong: /proc/bus/ is not syncronous, so
scripts still need to wait (they may use the wait_for_file function from
/lib/hotplug/hotplug.functions). OTOH, RUN is still the correct keyword
to use, because PROGRAM has different semantics (and you must always use
+= unless you know better).
This looks like the same issue of #334068, which I am reassigning for
libsane (I'm sorry for not getting it right the first time).

I need newer kernels before a debian package is available, and anyway I
will not use debian kernels again as long as they will break drivers
by removing uploadable firmwares.

Because the rule matches on many events, among them BUS=="usb".
The correct rule to change the /dev/bus/usb/ device permissions would
be:
SUBSYSTEM=="usb_device", SYSFS{idProduct}=="0039", SYSFS{idVendor}=="045e", \
GROUP="plugdev"
(660 is the default.)
