Huawei E220 with Ubuntu

To run the Modem in Ubuntu install umtsmon and afterwards execute the following commands using the shell:

sudo rmmod usb-storage
sudo modprobe usbserial vendor=0x12d1 product=0x1003
sudo /usr/local/bin/umtsmon

This is necessary because unforunatelly the modem will not switch to it’s modem mode until the correct windows drivers are installed.
