I have been using Ubuntu 13.04 since last two months and I have problem mounting my USB dongle. I have Lenovo G-580 series laptop. It has 3 USB ports which are 3.0. When I attach dongle to one of the three USB ports the device gets mounted immediately but in the other two ports I have to reboot the OS while the dongle is attached to the laptop in order to mount it and connect to the internet. My dongle is of ZTE. I don't get what is going wrong.


If you are facing a problem that your computer doesn’t recognize the device then run the command below:

sudo apt-get install usb-modeswitch usb-modeswitch-data

    Running the above command tells me following: usb-modeswitch is already the newest version. usb-modeswitch-data is already the newest version. – iammurtaza Jul 11 '13 at 3:20
