The modules has still a few problems:

• it required /system/etc/init.gprs-pppd for pppd.

  !/system/bin/sh

  PPPD_PID=

  /system/bin/setprop "net.gprs.ppp-exit" ""

  /system/bin/log -t pppd "Starting pppd"

  /system/xbin/pppd $*

  /system/bin/pppd /dev/ttyUSB0 115200 nocrtscts usepeerdns debug nodetach ipcp-accept-local ipcp-accept-remote defaultroute

  PPPD_EXIT=$? PPPD_PID=$!

  /system/bin/log -t pppd "pppd exited with $PPPD_EXIT"

  /system/bin/setprop "net.gprs.ppp-exit" "$PPPD_EXIT"

• 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/block/sr0 start usb_modeswitch

  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

  service pppd_gprs /system/etc/init.gprs-pppd user root group radio cache inet misc disabled oneshot

  service usb_modeswitch /system/bin/usbs user root disabled oneshot

• Edit system/build.prop ,add:

  for 3g

  rild.libpath=/system/lib/libhuaweigeneric-ril.so rild.libargs=-d /dev/ttyUSB2 keyguard.no_require_sim=1
