How to make new modem work?


Using Ubuntu 9.04 in dual boot with Win XP, I changed my PCI Softmodem for a USB modem US Robotic 5637 compatible Linux. My ppp internet and e-mail account are configured but there is no talk to the new modem. I even removed the PCI board from the computer but nothing happens, still offline. In Win XP the modem works perfectly. Any suggestions?
Thanks

According to http://www.ubuntuhcl.org/browse/sear...-by=&keywords=, this modem chipset is not compatible with Ubuntu.

Check if you have hwinfo. Open a terminal, and try hwinfo -modem or hwinfo -usb
If it isn't recognised, install hwinfo from a terminal - sudo apt-get install hwinfo
Otherwise, use lsusb -v (if you have it -- can't verify if this is in Ubuntu)

From the output from one of these commands you should be able to see if your hardware has been picked up correctly.

Some other info that might be useful - https://help.ubuntu.com/7.04/interne...-internet.html - note that this is for 7.04 - but it should provide a rough guide.

Thanks for your answer.
Using lsusb I find this:
Bus 001 Device 002: ID 0baf:0303 U.S. Robotics, followed by a lot of data but ending by this:
Can't get device qualifier: Operation not permitted
can't get debug descriptor: Operation not permitted
cannot read device status, Operation not permitted (1)
Using lsmod I found among other things: cdc_acm, supposedly needed from the readme file of the modem CD.
I also checked in /dev and found: /dev/ttyACM0, spécify by US Robotics and attached it to my ppp configuration to access the modem as suggested in readme. Still doesn't work. I can't install hwinfo, nor wvdial or minicom, those are packages Synaptic must get through the internet. I tried it manually by downloading through Win XP but it doesn't work, dependencies files always missing, must come as a package. US Robotics says it has been tested for Ubuntu 7.04, any other suggestions?

according to the installation quide need CDC ACM module loaded in your kernel. At a command prompt try
Code:
sudo modprobe CDC ACM
or maybe
Code:
sudo modprobe CDC
and then
Code:
sudo modprobe  ACM
and see if you can see the modem then
may have to unplug and plug back in modem after modules or loaded

did you unplug and plug back in your modem after you ran modprobe. go back into the ppp configuration to the modem section and see if the modem is picked up.

in a terminal
Code:
sudo modprobe cdc_acm
lsusb -v
if your modem isn,t listed in lsusb try unplugging and plugging back in to the same port or a different port. each time after plugging back in do
Code:
lsusb -v
and see if your modem is identified.

Yes it is. In reading a lot I think my problem comes from ppp because I checked the box for the connection before configuring it(I thougt the box was for choosing what I wanted to configure). I uninstall completely the gnome admin. package to start from scratch but the first ppp configuration is still there and I can't find where it is. Is there a way to clean slate for ppp modem configuration and make a new one like I was supposed to? Unless there is another solution. Thanks

does
Code:

T Drakeo: The readme file on US Robotic CD recommand making: ln -s /dev/ttyACM0 /dev/modem. After configuring ppp as you said I got this message after trying to connect with pon like colorpurple said:
/usr/sbin/pppd: In file /etc/ppp/peers/provider: unrecognized option '/dev/modem'
How can I remove that link? -ln? Here is attached the dmesg report. Thanks
