Moved to Other OS/Distro Talk.

Maybe you need drivers from contrib or non-free for the gsm modem.

An exaple from my /etc/apt/sources.list (in debian):

Code:

---

deb http://mirrors.nl.kernel.org/debian/ wheezy main contrib non-free

---

Can you post the terminal output of the following commands (in a code box please, to avoid annoying smilies)

Code:

---

uname -a

---

Code:

---

lsusb

---

Code:

---

cat /etc/apt/sources.list

---

Code:

---

sudo lshw -short

I've got to say installing drivers in linux always gives me a headache. :) I'm so used to plugging things into my machine that just work without having to install anything, that I feel a little lost when it doesn't.
