Resolving Issues with Conexant USB Modems on CentOS

Troubleshooting a working Conexant USB modem under Linux can be an arduous task, especially when compared to the relative ease of use found in Windows. This article will guide you through some common problems and their solutions for getting your external or internal Conexant CX93010 ACF USB modem up and running on CentOS.

Step 1: Identify Your Modem

Before diving into troubleshooting, it's essential to confirm that you indeed have a Conexantis the list of recognized devices. To do this:

a) Open a terminal window as root (or use `sudo` if prompted).

b) Type ` lspci | grep -i cx93010`

c) If your modem is detected, its vendor and device ID should be displayed in the format 'Bus 004 Device 004: ID 0572:1300 Conexant Systems (Rockwell), Inc.'

Step 2: Load Required Modules

After identifying your modem as a Conexantis device, you'll need to load two kernel modules for it to function:

a) Type `modprobe option` and press Enter.

b) Next, type ` modprobe cusecxfer`

c) If the modules have loaded correctly, no error messages should be displayed.

Step 3: Configure Modem

With the necessary drivers in place, you'll now need to configure your modem for use:

a) Open a terminal window as root (or use `sudo` if prompted).

b) Type `modprobe serial Hayes`

c) If asked whether you want to continue with this action, type 'yes' and press Enter.

Step 4: Configure Modem Port

Now that the kernel modules have been loaded, we need to create a modem port for your USB device:

a) Open a terminal window as root (or use `sudo` if prompted).

b) Type `cat /dev/usb/tty* | grep -i serial0`

c) Note down the device name of the port corresponding to your external or internal modem.

Step 5: Configure Modem Port in dial-up

Finally, you'll need to configure the new serial port as a modem:

a) Open 'System' > 'Preferences' > 'Network Connections'

b) Double-click on 'Modems' and then click on '+'

c) Select 'Other CDMA/1xPPR modem' from the list

d) In the 'General' tab, enter any desired name for your new dial-up connection.

e) Click OK to save changes.

Step 6: Test Your Modem

Now that you've completed all of these steps and restarted your system once more, you should be able to test your modem by attempting a simple call or sending an email using the built-in `wvdial` client:

a) Open a terminal window as root (or use `sudo` if prompted).

b) Type ' wvdial '

c) If everything has been configured correctly, you should now be able to browse the internet via your Conexant USB modem.

Troubleshooting and configuring a working external or internal Conexantis-based USB modem under CentOS can be an arduous task. However, by following these simple steps outlined above, you'll have your modem up and running in no time. Remember always to refer back to the official documentation for any further assistance if required.
