usb v92 modem

Hi Guys, I'm really new to this, and have done a lot of searching but nothing has helped. I have a Netcomm Roadster V.92 USB Modem which I was hoping to use with my new instal of Redhat9, however I have no idea how to get it working. I tried to set it up and was told no modem detected, so now I am stuck. There are no Linux drivers available on the manufacturers website, and I'm wondering if you can give me some step-by-step guidance on how to try to get this working

Thanks, Ches

This should really be a simple exercise, and not require spending hundreds of dollars on new modems. I guess this is why Linux is never going to overtake Windows. Linux - Free as in pain in the arse.

Simple - e-mail the manufacturers and ask why they don't write drivers for Linux. They do for Windows. If you find a piece of hardware that has no Windows drivers written for it, whose fault is that? Windows? I think not.

It is always a wise move to check hardware compatibility before installing any OS.

I saw a couple of advertisements for that modem on the Internet that say it works with Linux. However, I did not see where he could get get a driver. It also did not say if he needed one or not. Instead of using an external USB modem, I use an external serial modem. With it, I did not need to add a driver. I used the command neat to install my modem in Red Hat. Red Hat 9 could not detect the presence of my modem, but it then asked me where it was connected. I selected the appropriate choice from the options it gave me and it then said I had a generic modem and accepted it. It then went on to ask me for information about my internet provider such as the phone number. After that I was able to connect to my Internet provider. I was never asked to install a driver. Is there any chance that his external USB modem could also be like that or would it require a special driver? At least some of the external USB modems are winmodems and do require special drivers. I see his original post said his modem was not detected. In both Red Hat 9 and Windows 2K my external serial modem was not deteced but was accepted as a generic modem and it works good.

P.S. I did not notice fancypipers small link in his post just before making my post above. It has some good information.

From the link I posted:

Code:

Suse 7.1 Netcomm USB Roadster external modem.

Requirements that I can think of include

Kernel support for USB- I use the USB -"uhci" module.
Kernel support for a modem driver - I use the "ACM" module.
Use /var/log/messages to monitor the installation.

In Wvdial I use the link
/dev/modem -> /dev/ttyACM0

Open an x terminal and make sure the modules are loaded:

Code:

fancy@uilleann $ su -
Password: 
root@uilleann # lsmod
Module                  Size  Used by    Not tainted
<unneeded snip>
hid                    21344   0  (unused)
input                   5984   0  [mousedev hid]
ehci-hcd               19520   0  (unused)
usb-uhci               24452   0  (unused)
usb-ohci               20736   0  (unused)
usbcore                73216   1  [hid ehci-hcd usb-uhci usb-ohci]
root@uilleann #

Make sure those modules are loaded as well as the "ACM" module module (sorry, I can't tell you how to load it as I have never used it) mentioned.

Make a symbolic link from the device to one called modem

Code:

root@uilleann # ln -s /dev/ttyACM0 /dev/modem

If everything is loaded correctly, you should be able to connect using /dev/modem or /dev/ttyACM0
