The modules has still a few problems:

* required modify init.rc add:
	on device-added-/dev/ttyUSB0
	chmod 0777 /dev/ttyUSB0
	on device-added-/dev/ttyUSB1
	chmod 0777 /dev/ttyUSB1
	on device-added-/dev/ttyUSB2
	chmod 0777 /dev/ttyUSB2
	on device-added-/dev/ttyUSB3
	chmod 0777 /dev/ttyUSB3
	on device-added-/dev/ttyUSB4
	chmod 0777 /dev/ttyUSB4
	on device-added-/dev/ttyUSB5
	chmod 0777 /dev/ttyUSB5


	on boot
	service ril-daemon /system/bin/rild
	socket rild stream 660 root radio
	socket rild-debug stream 660 radio system
	user root
	group radio cache inet misc audio


* Edit system/build.prop ,add:
	# for 3g
	rild.libpath=/system/lib/libhuaweigeneric-ril.so
	rild.libargs=-d /dev/ttyUSB2 -v /dev/ttyUSB1
	keyguard.no_require_sim=1

	pppd must be suid ROOT, and kernel must include ppp support compiled in
	/system/etc/ppp/ip-up and also /system/etc/ppp/ip-down must also be suid ROOT

	You also need the following files in /system/etc/ppp
