Strange Problem in Ubuntu I have installed Ubuntu 12.04 64 bit version in my Desktop and when I plugged in 2 different USB modems they were promptly recognized and was able to configure them using network manager. But the same cards refused to be recognized on a Toshiba Laptop.

Running lsusb for one of them(desktop)

    cpcadmin@cpcadmin-SD30V10:~$ lsusb
    Bus 005 Device 004: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800 (HSPA modem)
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Running lsusb after a few seconds

    cpcadmin@cpcadmin-SD30V10:~$ lsusb
    Bus 005 Device 005: ID 12d1:140b Huawei Technologies Co., Ltd. EC1260 Wireless Data Modem HSD USB Card
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Its only after the same card is recognized as 140b by ubuntu was I able to use the network manager to configure the internet.

The same card when plugged into the laptop would just stop with the first step where it was recognized as a 1446 device.

Any idea as to what I need to do in the laptop?

Thanks in advance Regards Vivek

Hi Thusitha,Thanks for your feedback. My problem is that the Desktop running 12.04 recognizes by card as 140b while the laptop running the same version of 12.04 recognizes it as a 1406. –  v_radhakrishnan Nov 29 '13 at 9:46
