How to make the Vodafone Internet Key Huawei K3765 work on a fonera2n

• install the new version of kernel 2.3.5 (dev version)
• install usb_modeswitch, lsusb and libutils packets

• put in /etc/usb_mdoeswitch.conf the following istructions:

  # Huawei K3765
  DefaultVendor= 0x12d1
  DefaultProduct= 0x1520
  TargetVendor= 0x12d1
  TargetProduct=0x1465
  MessageContent="55534243123456780000000000000011060000000000000000000000000000"

• go in the directory /dev/ and execute:

  mknod /dev/ttyUSB0 c 188 0
  mknod /dev/ttyUSB1 c 188 1
  mknod /dev/ttyUSB2 c 188 2
  mknod /dev/ttyUSB3 c 188 3

  (I'm not sure, if 188 isn't the good, try with 189, this is the entry point of the usb)
• reboot

• execute: usb_modeswitch

• execute:  echo "0x12d1 0x1465" >/sys/bus/usb-serial/drivers/option1/new_id 

• At this point the fonera will properly recognize the /dev/ttyUSB* and the 3G modem. Add in the /etc/init.d the script which will execute usb_modeswitch and echo... on boot and link it to /etc/rc.d

Hope this will help you.
