OpenWrt package and udev rules

[Bjørn Mork]

Hello!

I noticed that the package comes with the udev rules.  Why is that?  The
are explicitly installed by the makefile install rule:

define Package/modemmanager/install
        $(INSTALL_DIR) $(1)/lib/udev/rules.d
        $(INSTALL_DATA) $(PKG_INSTALL_DIR)/lib/udev/rules.d/*.rules $(1)/lib/udev/rules.d


are these used anywhere?  If not, then I suggest dropping them.  This
will never be a small package, obviously. But I still believe the
OpwnWrt way-of-things is to strip away anything not absolutely required.

It would be nice if this functionality actually was there, though..  I
am having some problems when booting my combined console server and
modem manager OpenWrt box.  ModemManager probes ttyUSB[0-3], which are
supposed to be used by conserver:

ModemManager: hotplug: error: modem not detected at sysfs path

It would be nice to avoid this by blacklisting this device, like I would
have done on a system with udev.  Is there any way to make the OpenWrt
hotplug scripts avoid a specific USB device?
