Few weeks ago I bought HP mini 5102 which has built in Gobi un2420 (Mobile Broadband Module). Everything works out of the box on Windows 7 with HP software connection manager. However, the Ubuntu Lucid is “more complicated” than Windows 7.

There are a few things you should know before you will be able to use it on Ubuntu:

1. step) Download my QUALCOMM directory from Windows 7 (Qualcom.zip)

2. step) Create a new folder containing QUALCOMM firmware

sudo mkdir -p /lib/firmware/gobi

3. step) Unzip previously downloaded Qualcom.zip folder and copy country code files to “/lib/firmware/gobi” directory

sudo cp -pi /QUALCOMM/Images/HP/6/* /lib/firmware/gobi
sudo cp -pi /QUALCOMM/Images/HP/UMTS/* /lib/firmware/gobi

Use files from 6th directory, if you are from Europe. On the official HP website you can choose which package suits your needs.

In my case there are 3 files copied to /lib/firmware/gobi. Here is the output of this folder:

4. step) Download Lucid patch, unzip it and than install it

tar -xvzf qcserial.tar.gz
cd qcserial
make
sudo make install

5. step) Download latest Gobi loader (latest gobi_loader-0.7.tar.gz)

tar -xvzf gobi_loader-0.7.tar.gz
cd  gobi_loader-0.7
make
sudo make install

6. step) Restart your computer and than do this:
sudo pkill modem-manager

sudo /lib/udev/gobi_loader -2000 /dev/ttyUSB0 /lib/firmware/gobi/
