Ubuntu 8.04 with a USB modem

[ericeclifford]

Hi I have a USB modem, but I can't figure out how to get the computer to see it.

The make is a rosewill, and I heard reports it worked on 8.10 and 9.04, but Could not get how to it to work on 8.04.

From research people say it should show up on /dev/ttyACM0 but I do not see that, nor do I see a /dev/modem when I do wvdial.

Any help?

Hi ..im no expert in modems or linux for all that matters but i do have a similar problem with an USB modem ( in fact with two..)
from what i've learned...you should consider doing a search of with the Modem Model and you would find (with luck) more than one thread related to it.

looks like there is more than one way to do everything on linux :) .. good luck ..

regards..

My advice is to get a Router/hub. I had a modem to start with and although I did get it going it was a pain whenever I upgraded. Since I moved to a router I've had no problems, mine was only £30 and has proved reliable for several years now.

i had some problems with my usb modem too, but i have solved

Can you give us the output of :

sudo lsusb -v

maybe i can help you with this

[beastrace91]

Many USB modems are "multiple usb" devices and require "flipping" before you can use the modem part of them - give this a try (http://www.draisberghof.de/usb_modeswitch/) if this may be your issue.

A quick search finds this posting (Post #3)

You should ALWAYS configure wvdial, and during the configuration it searches
for all available modems. It should locate your USB Modem......

And once wvdial has located the USB Modem you are going to need a guide to set
up a few other things:

USB port check out the following:

Finally, when everything is working download Gnome-PPP and set it up for easy
GUI Dialup connecting.

Thank you guys for your support, I will try all these steps and repost, once I get to my lin comp.

This is the output of the lsusb -v

Also the modem is detected in 9.04 but not 8.04.

It is a RNX-56USB Rosewill Modem

[ericeclifford]

Ya I still can not figure out how to do this, it is a real pain.

I edited my above reply with more details, in case anyone has more luck then me.

I tried configuring wvdial, usbmodeswitch, still nothing.

[lkraemer]

Post the contents of:
/etc/wvdial.conf

[ericeclifford]

well I was going to use something like this, but I could not even detect my modem yet so I have not signed up to a provider...

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,”IP”,”gpinternet”
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
ISDN = 0
Phone = *99***1#
Username = gp
Password = gp

This being an example on a site I found that uses a USb modem in 8.04.



But I also did this
lsusb got me this.

Do not quiet sure what it means exactly, but the conexant Systems should be my USB modem, but I am not quiet sure what the BUS/Device stuff means, I am going to do more research, just thought I would update.

[ericeclifford]

Any more advice guys, thanks again for the support thus far.

[anewguy]

I would suspect that before you can actually use that USB modem, you are going to have to install a driver for it first. If you have a Windows driver or disk for it, let us know. In the mean time, I'll go hunting for some sort of driver.

Dave :)

[anewguy]

A quick google search on the USB vendor/product id (the 0572:1321 on the lsusb line that shows your modem) turned up this page:

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

If you have a way (direct connect) to be on the net with the computer while looking at this site, be sure your USB modem is connected and proceed to the download. It has an option there to download an automatic installer. Be sure to read the installation instructions, and keep in mind that Ubuntu is debian based, so follow the instructions for that.

If you have any problems/questions or anything at all, just post back.

You'll need the driver before things like wvdial can actually see the modem.

Dave :)

[ericeclifford]

But in 9.04 it automatically sees it, does that mean 9.04 has the driver installed by default?

[ericeclifford]

This worked, thank you, it finally sees my modem $$ :0

[anewguy]

If 9.04 automatically sees your modem, then yes, it has the driver or at least a driver, with it.

Glad you got things working in 8.04.

A small side note to others who may have been following this:

A USB modem is normally going to be a "Winmodem", meaning that it is not a stand alone modem so a lot of the processing has to happen in software (the driver). In this instance, the driver had to be installed before the modem could be used. Yes, lsusb (list the known USB devices) showed the device - this simply means it recognized the hardware, *NOT* that the hardware will work just out of the box.

A lot of non-serial (serial modems are stand alone modems that plug into your computer via a serial cable) are "Winmodems" and require software to make them work. There are lists on the net of modems that are known to work with Ubuntu and Linux in general and if a driver is needed. This topic has been covered many times before, but just to reiterate - check the online lists for supported modems (or buy a completely stand alone hardware modem) before buying a modem for use in Ubuntu, and in Linux in general.

Dave :)
