Sierra Wireless 320U USB-to-WWAN modem is not detected (needs updated drivers from manufacturer website)

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.3 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.3-rc2 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.3-rc2'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

Tested with upstream v3.3-rc4 and the device is still not detected.

Tested with upstream v3.3-rc5 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc5-precise/) and the device still not detected.

I can confirm that the updated drivers from Sierra Wireless website work on v3.3-rc5. After installing the updated drivers, the device is detected and a wwan0 interface is created.

Do you know if the manufacturer is working to get the latest drivers upstream?

We generally ask bug reporters to first request that the driver be added to the upstream kernel. This can be done by mailing the Linux Kernel Mailing List or opening a bug at bugzilla.kernel.org.

I sent an e-mail to <email address hidden> asking if they could submit their latest driver to the linux kernel, but I haven't yet received any response. I've filed a bug upstream on bugzilla.kernel.org at https://bugzilla.kernel.org/show_bug.cgi?id=42830

I've now sent an e-mail to <email address hidden> as per GregKH's instructions on the bugzilla bug.

Relevant patches:

Greg-KH's commit should appear in linux-next sometime within the next week.

Note that these patches do not implement the full updated driver from SierraWireless. They only add the new device ID to the existing sierra drivers, so are lacking any new features that are in the latest drivers from SierraWireless.

The two patches required to fix this bug are now in linux-next.

The two patches have now arrived in linux-stable.

Also picked up by Linus' tree. It would be great to get this fixed in a SRU for Precise.

Presumably the other one is in there somewhere too.

Yep, there it is (in the 3.5 kernel):

If it is in the stable 3.2 tree it will eventually come to Precise as an SRU.

Hi, as indicated above I need a little help getting a grasp of things I can't point and click with a mouse, however I've tried updating the development kernel as described above expecting that the patches now in linux-stable would have taken effect, however I'm still not able to connect with the Sierra Wireless AirCard 320U modem. Hope you're able to give me a clue as to how I can do that, thanks?

Please don't mark bugs as private unless there is confidential information in the bug report.

This has already been fixed, as the patches for this are now included in the current released kernels for Ubuntu 12.04 and 12.10. You shouldn't have to do anything with the driver from Sierra Wireless. It should "just work" and be detected automatically when you plug in your usb modem device.

If you have previously installed a separate driver (eg. from the Sierra Wireless website), then you will need to uninstall that to revert to the driver included in the kernel.

If you run "modinfo sierra" and "modinfo sierra_net" from a Terminal window, you should see the following driver versions:

$ modinfo sierra
filename: /lib/modules/3.5.0-19-generic/kernel/drivers/usb/serial/sierra.ko
license: GPL
version: v.1.7.16
description: USB Driver for Sierra Wireless USB modems
...

$ modinfo sierra_net
filename: /lib/modules/3.5.0-19-generic/kernel/drivers/net/usb/sierra_net.ko
license: GPL
version: v.2.0
description: USB-to-WWAN Driver for Sierra Wireless modems

Hi, thanks for your advice Tom, sorry for not following protocol with the private/public thing, I'm still learning how it all works. I'm puzzled though, as the only reason I've tried anything new is the Sierra modem doesn't work. It works fine on a Windows PC, but not this Ubuntu machine. As I pointed out earlier, I'm a bit of a novice with the Terminal, but I'm prepared to have a go at anything with a bit of advice. If you were able to give me a clue as to what else to try I'd appreciate it. Thanks.

Can you post the output of "modinfo sierra" and "modinfo sierra_net"? Run those two commands in a terminal window without the surrounding quotes.

Tom, thanks again for your help. Below is the "modinfo sierra" and "modinfo sierra_net" you requested. I hope it helps. I've had some more attempts to make it go. It is now being detected as a Sierra Wireless Aircard 320U, I'm wondering if the problem is really an incorrect description of the plan. Is it possible to get the modem to report back it's settings?

I know it's a Telstra 4G modem and the person I'm trying to help has given me their bill but no matter what I try calling it, it simply won't connect. I've scoured the Telstra website trying to ID the plan, but I'm just going in circles. I have a Telstra Next G modem I've never had an issue with, so I don't understand what I'm doing wrong.

I have learnt a few more commands when using the terminal, I suppose that's plus! Anyway, I hope you can help me, thank you for your time. Chris.

That looks like the correct drivers. If you run "ifconfig -a" do you see a wwan0 interface listed? If not, then I'm not sure what else to do as I am running from one of these devices right now.

If the wwan0 interface is there then it should be appearing in Network Manager. There should also be a new option in the network menu for "Enable Mobile Broadband". You will also see a bunch of stuff appearing in the syslog at /var/log/syslog after plugging in the device.

Hi Tom, I'm online using the Sierra modem. No good explanation for it. I kept trying various different combinations of Telstra log in options and finally tried to connect using my Next G USB modem. It connected immediately, so that eliminated interference or low signal. I shut down immediately and connected the Sierra in one of the rear USB ports. Connected immediately. So then I tried a process of elimination and discovered the Sierra won't run on the front USB ports, I assume it doesn't get enough power, don't have any better explanation. Once again thank you for your help and patience in helping try to solve this problem, hope this helps someone else. Chris.

i had the problem of Sierra 320U Aircard to work with my Win 7 OS, anybody give some advice??
