Windows 8.1 Ent. Helix - Sierra Wireless EM7700 device error code 43

System:
Helix 3701XXX
Windows 8.1 Enterprise 64-bit
Third Apps installed
Latest Lenovo Drivers installed
Problem:
Sierra Wireless EM7700 device experiences device code error 43 or not “USB device not recognized.” There are also times where there are two or more instances of the same device in Device Manager.
When the problem occurs, users are unable to see the mobile broadband device under Network connections menu (Charms menu->Settings->Network Connections). Installed drivers on system: Sierra Wireless QMI Lenovo Driver Package 2.6.1.209.0. Experienced this issue with the Lenovo pre-load image and corporate image. The problem has been reported by 10+ users/systems;
When it occurs:
The problem is intermittent; it often occurs after waking the system up from sleep or starting the system from a cold boot. As a workaround, the user has to restart the system a couple to several times in order for the device to be recognized.
Wondering if anyone else has been experiencing this on the Helix 3701XXX Windows 8.1 Enterprise? Any advice is appreciated.

I get similar problems with the Ericsson C5621 wireless card.
To be honest, almost every 3G\4G internal card I've experienced (in Dell, Toshiba and now Lenovo) have suffered from the same two problems (when used against UK mobile providers):
i) issues resuming from sleep - typically the card not responding or not found until doing another sleep\resume or power cycle
ii) issues when moving quickly between cells (e.g. if using the device on a train etc.), when the card will stop transmitting traffic although claims to be connected, and then will become unresponsive attempted a disconnect and reconnect. Again power cycling the card (via sleep\resume, reboot, or occasionally disabling\renabling or uninstalling\reinstalling the driver) will resolve this.
Given that these cards are typically used in mobile devices where sleep\hibernate and being on the move are pretty common scenarios, it is frustrating that the 3G\4G hardware companies still can't get them to work reliable.

    Hi,
    The error code  0xC004E003 means that the Software Licensing Service reported that license evaluation failed.
    We may need to involve the phone activation center and check if they can resolve the issue:

  • Problems Uninstalling Sierra Wireless Software (LAUNCHD errors)

    How did you "uninstall" that software? If you just trashed what you thought were the components of the software, it would have been better to use an uninstall utility or option if that was available.
    Look in the /Library (at the top-level of the boot volume, not the one in your home folder) for these folders:
    - LaunchAgents
    - LaunchDaemons
    - StartupItems
    One of those may have a file related to that software that's still attempting to launch it. Once you've found the culprit, delete it.

  • Using VZAccess Manager v7 With Sierra Wireless SB555 Embedded Device

    We have several Panasonic CF-29 Toughbooks with embedded Sierra Wireless SB555 devices. Up to now we were running VZAccess Manager v6.9 on these laptops without any issues.
    For consistency sake we want to upgrade VZAccess Manager in these laptops to v7. From what I could determine VZAccess Manager 7 should work with the SB555 devices. This is where I came across an issue.
    After installing VZAccess Manager v7 the Verizon Wireless - VZAccess dial-up networking connection was not created. Trying to connect failed: Connection not available.
    I manually created the connection and I was able to connect. The problem is that whenever I use Detect Device VZAccess Manager deletes the connection and a new one is not created.
    I have a temporary solution by creating a connection named BACKUP Verizon Wireless - VZAccess and then when needed just duplicate this backup connection and rename it properly. At least that is a solution in the lab.
    This leads to 3 questions:
    Is there a way to make VZAccess anager create the connection as it normally should?
    When the automatic area coverage updating takes place, does that trigger a Detect Device? If it does not I guess I am safe to believe that the connection will not be deleted in the field.
    Is there a way to reduce the time between the coverage area updates so that I can test this in the lab without having to wait days or weeks for it to happen on its own?
    Thanks!

    I would recommend uninstalling the current version of VZAM on the PC, and installing the VZAM software from www.vzam.net. I have listed the instructions below on navigating to the software.
    Once on the VZAM home page, select supported devices on the red menu located on the left hand side of the screen
    Scroll towards the bottom of the page for Laptops with Embedded Verizon Wireless WWAN Module
    The 4th selection from the top is labeled “Panasonic Toughbook with global module.” Click on the version number that fits your Windows OS
    Enter your wireless number
    Before you download, check the two links below on whether you will need drivers for the WWAN device, or the Toughbook itself. I have listed the link below: 
    http://panasonic.com/toughbook/support
    http://www.vzam.net/UploadedFiles/Pan03_RevA_Driver.exe
    If you are okay with the drivers, you can proceed to download the VZAM software by clicking the red download now button. Once selected, save the file to your desktop and install the software
    ***Download version 7.2.9 (2470a) for either Windows XP/Vista or Windows 7
    ***If step 1 is completed successfully (the drivers installed, the device was found, and the set up completed), the VZAM network connection will be automatically built.
    2.      At the point that the automatic coverage update initiates, it has already detected the device. (If a device is not detected, you will not be able to activate it or update the coverage information.)
    3.      To reduce the amount of time a coverage update can take, you can periodically perform a activation on the device. This can be done by selecting the “options” tab at the top of the VZAM menu, and select “activation”. This process will update the PRL (Preferred Roaming List) and coverage area.
    I hope this information was helpful.

  • Error Code C800044E while Windows Vista update

    Please can someone help me with a problem that I have trying to download any updates for windows.
    Every time I search for downloads the error code C800044E appears.
    I dont know much about laptops but can follow instructions.
    I have been on microsofts website and done as they advised ie safe mode etc but nothing works.
    Please can anyone help me...Ive had the laptop for a couple of yrs and I want to give it to my young children to use for schoolwork etc but it keeps crashing.
    I have done several scans for both virus & spyware etc but they come up clear.
    Hopefully someone can help me and talk me through how to sort this problem out with clear steps lol...
    many thanks

    I know, it sounds stupid now but you can also visit some Microsoft forum and check for solution.
    In my opinion Toshiba has nothing to do with this.
    By the way: you should disable automatic update. Before you start update check the list of all stuff offered by Microsoft. Do not update some driver.

    Hi @emma22 
    I would like to do my best to help, but please bear in mind the issue you are expressing is an inquiry for Microsoft not HP. I did find something I think will be most helpful, and I hope it resolves the issue, but if the issue persists, or you have additional questions, it might be best to reach out to the Microsoft community.
    Here is what I found; HomeGroup from start to finish.
    In the top right hand corner of the article, you can change it from WIndows 7 to Windows 8. I hope this helps.

    Latest Lenovo Drivers installed
    Problem:
    Keyboard and Touchpad on the keyboard dock intermittently stops working altogether. The UltraNav pointing device also reports device code 43. The user is unable to type or move mouse cursor. Sometimes the touchscreen will also not work when this problem occurs. The problem has been reported by 3+ users/systems.

  • Mac OS 10.6 cannot connect to my AT&T Sierra Wireless...help!!

    I just purchased my macbook pro OS 10.6 snow leopard today. My entire life ive used windows. all i would like to do is connect to the internet. I have the sierra wireless usbconnect 811 thru AT&T, i spent 3 hours at Apple with 3 different Genius bar guys and all they concluded was it is incompatible but if i do enough research online i could find a way....well ive spent 2 hours online and no luck. people talked about finding some telephone icon under networks but i cannot find that either. i feel helpless~

    Hi,
    Go to the Sierra website and look for their supporrt area. I did see Mac OS compatibiity, but it doesn't mention Snow Leopard. Most likely they haven't updated their software/hardware for 10.6
    The only mention of Mac OS here is 10.4. That was Tiger, two operating systems back from Snow Leopard.

  • Sierra Wireless USB card  will not connect

    I have purchased a Sierra Wireless USB card (AT&T USB Connect 881) to use with a iBook G4. The green power lites are solid green. However, I can not get a signal from AT&T. No one has been able to help solve this problem. I am ready to return it to AT&T for a refund.

    Thx for ur reply. I just checked the model of the USB adapter is Belkin Basic N150.
    The xp is able to see and identify the iphone wireless network and shows it in available networks with full signal strength. Once I click on connect then an alert message says that it is detecting network type pls wait. Then another message appears stating that "selected network may be no longer in range. Pls refresh the list and connect again"
    As suggested by you I will try it on windows 7.

I would like to use WWAN services in my country and I am going to understand that I must to change my current adapter to WWAN Sierra Wireless MC8775 HSDPA adapter. Is it right way and it helps and is it possible to change?
    Thank you and best regards,
    xAlexx

    Your provider may have their own WWAN software (in the case of Vodafone it is Mobile Connect, for AT&T it is Communication Manager, etc. Vodafone even have a Lenovo-specific version of their Mobile Connect).
    Or you can use Sierra Wireless' 3G Watcher.
    I don't work for Lenovo. I'm a crazy volunteer!

  • Sierra Wireless USB AirCard Support

    I have been evaluating the product for a bit now, and it seems pretty rock solid. I just started testing with some of out cellular broadband devices and have found an issue with one so far. the Sierra Wireless AirCard 875U is not recognized by ESM. It totally ignores and doesn't apply any policy to the adapter. no firewall or otherwize. Is this a known issue?

I get this behavior with a stock install and the default policy. I can attach my policy files if you still feel its relevant.
    I think this is a fairly huge issue, and could allow a user to totally circumvent the ZESM client and leave the machine fully vulnerable.
    Can you try the following:
    Create a location called wireless
    Select an icon for the location
    In Wi-Fi Management click the "Filtered Access Points" tab and enter the SSID of your Wireless AP (it is case sensitive)
    Save and publish the policy.
    Does the ZESM client change locations?

  • Sierra Wireless EM7345 ThinkPad 8 and 10 general issues

    This was posted as a reply to german forum but it was deleted Symptoms (mobile connection is connected)
     1. mobile connection randomly disconnects. It is possible to reconnect again. 2. when resume from Connected standby mode the mobile connection appears to be connected but it is dead. It is not possible to disconnect nor turn off the mobile connection, it is stuck. Windows restart is required to resolve it. 3. when resume from Connected standby mode the EM7345 composite device disappears at all from Device Manager and new unknown device '1 CDC' appears. Windows restart is required to resolve it. Note: Issues 2 and 3 occurs when running on battery only. I don't have any occurence when the tablet was plugged in AC, turned off (into Connected standby mode) and on, yet. I have already tried to reinstall the 1.6.10513.4153 driver, no luck. I have also tried to disable 'USB selective suspend' feature in driver settings and switch off GNSS device (because it has Sierra Wireless driver), no change. I have latest BIOS 1.24 (ThinkPad 8, 64 bit). It is hard to reproduce the case 3 but I have almost reliable steps: 1. uninstall current driver (even it is the latest version)2. restart3. install current 1.6.10513.4153 driver, select Custom Setup, make sure the 'WWAN Logging Tool' is selected, finish the installation4. restart 5. establish mobile connection6. go to Start menu, Intel group, start 'M.2 WWAN Logging Tool'7. press Start Trace button8. turn off the tablet (while the tracing is running) by power button, wait for a minute 9. turn on the tablet(repeat steps 8 and 9 multiple times, in case you can not reproduce it at the first time) EM7345 device disappears with typical unknown 1 CDC device. Yes, it is not a standard operation but it is easily reproducible with the same result. Similar issue is reported in other forum posts for ThinkPad 8 and 10

     Old firmware 1.1 that can not be updated to 1.2, read this thread http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T540p-Sierra-WWAN-EM7345-reliability/m-p/1839271#M106663 The 1.2 firmware might help to resolve the issue (although this post states it actually did not help). Technical details When the USB composite device (EM7345 = WWAN + GNSS) disappears it incorrectly identifies itself as VID = 1519, PID = F000 so Windows can not find proper driver for the device and displays it with (?) icon. If you remove the '1 CDC' device from Device Manager and perform 'Scan for hardware changes' this time it is correctly identified as VID = 1199, PID = A001 and installed (these tasks can be automated using devcon.exe command-line tool, so the fix wouldn't require OS restart everytime it occurs. It is still hack, not a solution). It looks like a firmware bug because the USB composite device and WWAN MBIM device uses Microsoft generic driver. Summary Given the price tag of ThinkPad 8 and 10 tablets, Lenovo should fix that because this is basic functionality failure. Disappearing WWAN device that needs full restart is really serious issue. And again, please diagnose and resolve the issue (hint , hint) instead of "try to reinstall this, try to reinstall that, replace this, replace that" advices. It leads to nowhere because the driver/firmware is buggy as it was in the past with Ericsson device. (copy of the post is stored)
