The drivers on the cd are quite old. Visit
http://www.eagle-usb.org/ and download the drivers 2.3.2.
Extract in your home folder the file and follow the installation guide step by step it's pretty easy.
After that you can use the follow commands
(as root)
#eaglestat
gives status for modem it will probably say to load the drivers to modem
#eaglediag -w -d
will load the drivers to the modem you will see it blinking unitl both leds will be on
and at last the magic command
#startadsl
don't use ./startadsl because ./ executes a script locally in the folder you are and since you installed it you can use it in every directory you are
At the installation watch if at ./configure
it tells you that a previous version has been found
then you must run
#make uninstall
before
#make
If it still don't work check if you can borrow a usb hub with external power supply to use it with the modem. It is known that dsl modems do require enough power and if you have many peripherals and a weak power supply (like 250W) it would be wise to check it.
If it still don't work then just reply and we will se what we can check also.
I just had a big problem with the same modem and I really don't want to happen to anyone else. Although the solutino was simple(no, not to buy another one).
