USB modem unrecognized on Compaq Presario M2000

[poltr1]

I recently purchased a Conexant USB modem to use in my Compaq Presario M2000 laptop. (The laptop already has a built-in modem that's really a Winmodem. ) I plugged it in, installed the driver, and it found the built-in modem....but not the USB modem.

I'm looking for commands and packages I can try to further diagnose and rectify this problem. This would be a nice-to-have so I don't have to boot up Windows on the laptop just to be able to use the modem in places that don't have wired or wireless internet.

Thanks in advance for your help.

Hi

I don't know much about this Type of modem , however to find if the modem is recognised

try these commands from the terminal

Code:

lsusb

this will give a list of devices connected to the usb ports

Code:

dmesg | grep -e "modem" -e "tty"

this will give the lines the modem will use

Code:

tail -f /var/log/syslog

used to monitor what is happening on the system

it would be helpful if you could post the results of the first two results

then possibly the modem will connect using wvdial

also which version of Ubuntu are you you using

thanks in advance

I'm using Karmic (9.10) on the Compaq laptop. Here is the outout from these commands.

hi

from the info it looks as if the modem is detected on the system
one of the problems with 9.10 Gnome ppp and wvdial are not installed at default
if you have alternate Internet connection try installing the above , then configure following details from this site
https://help.ubuntu.com/community/DialupModemHowto

if a alternate connection is not available

try the alternative way by ( pppconfig and the pon/poff ) , details at the above site

one way of getting gnomeppp and wvdial is to save the files from the debian site to a usb stick. then when on Ubuntu open the files and install, this should be automatic by clicking on the files

details here

http://packages.debian.org/unstable/net/gnome-ppp

don't forget the wvdial shown in the list

if you still have problems here is a site worth looking at

http://www.pcurtis.com/ubuntu-mobile.htm

Just had one thought / if there are problems with a conflict of the two modems try to disable the software/built in modem from the Hardware Drivers in the admin menu or from the bios settings

regards

I tried these commands and still had no effect. gnome-ppp detects the built-in modem at /dev/ttySL0 but not the USB modem when it's plugged in.

Looks like the only way I'm going to accomplish this is to use an external modem and a serial-to-USB adapter (since the Compaq has no serial ports).

Thanks for offering to help out.

hi poltr1;

google has been an interesting advance;

if I google on "ubuntu 0572:1329"

I get several things: eg this post

http://forum.eeeuser.com/viewtopic.php?id=7848

is this your device? as I see interesting there was a .deb driver for the device;

and from this thread

http://www.murga-linux.com/puppy/vie...809a2a9b53a12e

a couple of folks say they got it working on ubuntu (but that would be an older version .............)

alexfish is a man likes a challenge so he may be able to help you through the above

I am curious if you got wvdial installed:

what does

gedit /etc/wvdial.conf

give?

can you copy and paste the results back here?

[poltr1]

Yes, that's what my modem looks like, without the Zoom logo.

My /etc/wvdial.conf, with usernames and passwords edited out:

[Dialer Dayton]
Phone = 910-9803
Username = [[redacted]]
Password = [[redacted]]

[Dialer Buffalo]
Phone = 531-4070
Username = [[redacted]]
Password = [[redacted]]

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Modem = /dev/ttySL0
Baud = 460800
;Phone = 910-9803
;Username = [[redacted]]
;Password = [[redacted]]

This is after the changes made by wvdialconf.

[poltr1]

I looked at

http://www.linuxant.com/drivers/dgc/index.php

, downloaded the DGC modem driver, and ran it. The script detected both the built-in HSF modem and the USB modem.

After some code tweaking, I then removed the USB modem and tried the built-in modem. I was able to get a dialtone and dial out. So that problem is finally solved.

I will now try the USB modem on a Dell Latitude CpxJ laptop running Hardy. I'd been using a PCMCIA modem that was not detected by the scanModem script.

Hi

found some info

NetworkManager probes modems automatically to determine their capabilities. NetworkManager 0.7.x only probes known mobile broadband drivers to avoid interfering with non-3G serial devices. That does *not* include the generic usbserial driver, because it most often drives non-3G devices. To probe modems that are driven by usbserial with NetworkManager 0.7.x, edit the /lib/udev/rules.d/77-nm-probe-modem-capabilities.rules file and change the line:

DRIVERS=="option|sierra|hso|cdc_acm|qcserial|moto-modem", GOTO="probe"


to



DRIVERS=="option|sierra|hso|cdc_acm|qcserial|moto-modem|usbserial_generic", GOTO="probe"


and replug your modem. NetworkManager should then see it. If that still does not allow NetworkManager to find your modem, your modem may not yet be supported. Please file a bug and report the 'lsusb' output and other details of your device.

the link

http://live.gnome.org/NetworkManager/MobileBroadband

also check the read me file udev.d

[poltr1]

I didn't have this rules file, so I created it and added the line you suggested. It had no effect.

Since I was able to get the built-in modem working after installing the Linuxant HSF modem driver -- and got the USB modem working on a Dell Latitude CPxJ after installing the Linuxant DGC modem driver -- I'm willing to consider this topic solved. Thank you for all your help.
