UMTS Setup
This is a short description of how you could run a UMTS router on Raspberry
- Requirements
- Raspberry PI Modell B
- 5V/1A Power Unit
- Mobile Connect USB-Stick UMTS Broadband Huawei K3765-HV mit integr. GSM-Gateway
- Debian Wheezy
Kernel Info:
root@raspberrypi:~# uname -a Linux raspberrypi 3.6.11+ #474 PREEMPT Thu Jun 13 17:14:42 BST 2013 armv6l GNU/Linux
Required packages:
apt-get install usbutils apt-get install wvdial apt-get install usb-modeswitch
This is required because the Huawei Model comes with a included storage device
which is casuing trouble at startup.
- Edit: /etc/modprobe.d/raspi-blacklist.conf
- Add: blacklist sr_mod

USB Modeswitch Hack
Required to get detect the Modem during boot
- Edit /lib/udev/rules.d/40-usb_modeswitch.rules
Search for K3765:
# Huawei K3765 ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1520", RUN+="usb_modeswitch '%b/%k'"
- Copy the above settings into: /etc/udev/rules.d/41-usb_modeswitch.rules
