All done, exiting

One time connection established (before it I made some random steps in BIOS), but later all became as earlier. I found the same problems (http://ubuntuforums.org/showthread.php?t=1996734 and http://smackerelofopinion.blogspot.com/2012/02/3g-using-huawei-e1552e1800-hspa-modem.html) and made the same steps, but lsusb doesn't changes. Only one time it unexpectedly changed to 'Bus 002 Device 012: ID 12d1:14ac Huawei Technologies Co., Ltd. ' (as it must be using USB 2.0) and connection established, but I dropped down the laptop and modem was disconnected. I've never got working Internet via modem since that time, lsusb shows 'Bus 003 Device 016: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800 (HSPA modem)'.

lsusb doesn't change. One time driver was found, but this program couldn't finish and I stopped it by Ctrl+C. It doesn't change anything. Thanks, Vladiator.

There is no USB 3.0 involved, it's just a regular USB 2.0 mobile broadband modem. That said, get a mobile hotspot like one from the Huawei E5 series, it's the better choice. –  LiveWireBT Aug 16 '12 at 20:02
    
But it has worked. Why? –  Vladiator Aug 17 '12 at 10:33
    
Sometimes things start to work by accident, but reproducing and controlling the behavior proves to be a lot more difficult. I'd say that is lost valuable lifetime, therefore my suggestion. –  LiveWireBT Aug 17 '12 at 14:15
    
I can't use hotspots - my laptop has a problems with Wi-Fi too. Is there any USB 3.0 modems? –  Vladiator Aug 20 '12 at 13:16
    
This has nothing to do with USB 3.0 nor would it be the solution. I suggest you get a better WiFi card for that notebook, too. Like one from Intel. –  LiveWireBT Aug 20 '12 at 14:56

I found out accidentally that my Tata Photon E1552/E1800 does not work as a modem on Mint 13 if connected to USB 3.0 port, but works wonderfully when connected via a USB 2.0 port on the same machine.

In fact, when connected to the USB 3.0 port on the motherboard, it is detected as a 12d1:1446, and refuses to switchover as a modem. When plugged into a USB 2.0 port on the same motherboard, it is seen as a 12d1:140b, and the network manager automatically takes it up as a modem.

I tested it on another machine running XUbuntu and it gave the same results. Works like a charm on the USB 2.0 port, but not on USB 3.0.

Is there a reason for that behaviour? Because this is also happening with my Huawei K3765 in Ubuntu 12.04.2 LTS and 13.04. –  Leo Jun 6 '13 at 11:06

Try this: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/979697/comments/115 This worked for me on Ubuntu 12.10, but not on Ubuntu 13.04 (hix)

I had exactly the same problem after upgrade but after using this and reboot all went well again http://www.linuxportal.pl/newsbar/modem-huawei-e1820-problem-z-polaczeniem-id82041 I know it is in Polish but I found it easy to follow anyhow..

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Moreover, since the article is in Polish (as you mention), you should definitely translate that to English over here. Otherwise, this answer adds little value to majority of users of this site. –  Aditya May 26 '13 at 7:11
    
OK I am sorry, and the solution does not always work so it was hasty to say it solved the problem. So still there must be a more stable solution somewhere. –  user145989 May 28 '13 at 4:49
    
I have done more trials and it seems like I found a stable solution. I updated the kernel to 3.9.4 and now the usb dongle get recognized the right way, both on usb3 and on usb2 ports. I used this link upubuntu.com/2013/05/linux-kernel-394-released-for.html –  user145989 May 29 '13 at 4:32
