Manual Driver Installation- kernel 2.4.x.x

1. This setup assumes that you have installed the usbserial driver distributed on your CD according to the instructions in the driver installation readme file.

2. Open an xterm window unload the usbserial driver by entering (you will be required to enter the root password after entering this command):

"sudo modprobe –r usbserial"

3. On the terminal, load the driver to match your card product ID. Please lookup the proper product ID in Table 1.

Table 1. Novatel Wireless modem products identification number.

Novatel Modem Model Name Product ID
Merlin U730 and U740(Vodafone) 0x1400
Merlin U740 (non-Vodafone) 0x1410
Merlin XU870 0x1430
Merlin X950D 0x1450

Ovation MC950D

0x4400
Ovation MC990D
MiFi2352

Ovation MC996D

0x7030

Expedite EU740 0x2410
Expedite EU850D/EU860D/EU870D 0x2420

"sudo modprobe usbserial vendor=0x1410 product=0x[prodID]"

Where prodID is the proper product ID that corresponds to your modem card in Table 1.

Although it is not necessary to verify the result of running the command above, but if you want to be sure that the driver is now associated with your card, connect your modem to the computer, and run the following on the command-line:

"sudo dmesg | grep –i ttyUSB"

You should see something like: usb 5-1: generic converter now attached to ttyUSB0

usb 5-1: generic converter now attached to ttyUSB
