INSTALLING DEVICE DRIVERS
Installing Device Drivers
Installing on Linux
The Linux OS includes a generic USB driver for modems supporting CDC/ACM.
Multi-Tech tested the following Linux operating systems and all used port . If your system has another device using
this port, your port numbers may be different.
■ Ubuntu
■
Debian
■ Centos
To install the device on any Linux Kernel with CDC/ACM support, connect USB cable from the device to a USB port
on your computer. For most recent Linux distributions, there are no drivers to install.
Troubleshooting Linux
If Linux does not create devices, check for the kernel module:
# lsmod | grep option
If entries aren't found, load the kernel module with root privileges:
# modprobe option
If this returns an error response, such as # FATAL: Module option not found, the kernel module is not on your
system. You will need to build the driver.
Building a Linux Driver
If the Linux driver is not recognized by your system, the driver may need to be customized for your device.
Note: To avoid runtime loading, build the driver as part of the kernel instead of as a module.
1. Retrieve the appropriate kernel source code version for your system. This should be in your OS
distribution package. Unpack/install it.
2. In the root directory open the file: /drivers/usb/serial/option.c
3. Check for the existence of the proper #define statement.
#define TELIT_PRODUCT_CE910_DUAL 0x1010
4. If the define statement is missing, add it and then add the following in the usb_device_id option_ids[]:
{ USB_DEVICE(TELIT_VENDOR_ID, TELIT_PRODUCT_CE910_DUAL) }
5. Save changes and close the file.
6. From the unpacking root directory, type # make menuconfig
7. Configure the kernel according to the considered system configuration.
8. Browse to menu Device Driver > USB Support > USB Serial Converter support and select USB driver for
GSM and CDMA modems .
9. To start the build once configured, type # make
The kernel module option.ko is in the directory drivers/usb/serial. If the kernel was built previously, compile the
module by typing:
# make M=drivers/usb/serial
