I am using a CDMA 1x modem in india. I is extremely slow but comes with a unlimited package. So thats why I cannot leave it. I tried to configure it using network manager but it didnt work. The manufacturer is Linktop. The model number is 3197

The output of lsusb is- Bus 004 Device 002: ID 05c6:3197 Qualcomm, Inc CDMA Wireless Modem/Phone

Can anyone help me please?

You should contact the manufacturers with details of your operating system (which you haven't mentioned at all). – user25656 Jun 26 '12 at 15:43

good afternoon, I was going through your instructions, but in step 5, it writes this: rmmod: ERROR: Module usbserial is in use by: option isb_wwan. – Roman Roznovsky Jun 20 '14 at 16:43

1- Create a new File Named 0408:ea25 in /etc/usb.modeswitch.d and put Config Data:

sudo nano /etc/usb.modeswitch.d/0408:ea25
  • Copy the Below Text

DefaultVendor= 0x0408 DefaultProduct= 0xea25 TargetVendor= 0x0408 TargetProduct= 0xea26 MessageContent="5553424312345678000000000000061b004600000000000000000000000000" CheckSuccess=20

2- Add a new Rule to modeswitch rules:

sudo nano /lib/udev/rules.d/40-usb_modeswitch.rules
  • copy this line @ the end of the file:

    ATTRS{idVendor}=="0408", ATTRS{idProduct}=="ea25", RUN+="usb_modeswitch '%b/%k'"

3- Restart udev

sudo service udev restart

4- Add Detection Command to modprobe

sudo nano /etc/modprobe.d/mobily-lte.conf
  • copy the below text

    options usbserial vendor=0x0408 product=0xea26

5- Remove and Add usbserial config, This will Detect the Device

sudo rmmod usbserial
sudo modprobe usbserial

6- Configure a new Connection in Network Manager
