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
[2289]: <info> Modem: state changed (unknown -> disabled)

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?
