No Windows Phone 8 Detected

    Question

  • I'm trying to connect to my Windows Phone 8 device (lumia 920) to deploy an app unfortunately, I keep getting the error saying that no Windows Phone 8 device has been detected. I tried to developer unlock a Nokia Lumia 820 also which said that no phone was detected and to ensure IPOVERUSB was running, which it was.

    I have also tried uninstalling the devices in the device manager but that had no effect, each time I plug the 820 in (the device is recognised) and two versions of it are installed in device manger. No idea what is happening to cause this kind of problem.

    (I'm using Windows 8)

  • Hi All,

    If still having trouble connecting your WP8 phone device, please try the following troubleshooting steps:

    1. Open a command prompt and browse to this folder:

    C:\Program Files (x86)\Common Files\Microsoft Shared\Phone Tools\CoreCon\11.0\Bin

    Then run IpOverUsbEnum.exe (with the device unlocked!)

    2.Expected results:

    If the output is as expected, most likely it’s not an IP Over USB issue.

    3. If it reports RPC Server Unavailable, most likely the service is indeed not running on the PC.
    4. If it reports no connected partners found:
    - check the phone is unlocked
    - check it is available in explorer to drag and drop files
    - verify whether the USB device (i.e. the Phone) has been correctly detected and installed. This step is not trivial as it requires looking up the USB device (i.e. the phone) in the registry.

    The following example is based on inspection in the registry (regedit) of an installed Nokia 920 device. If looking for a different device, the difference will be in the VID (Vendor ID, represented as VID_vvvv) and PID (Product ID, represented as PID_pppp).

    1) Inspect the DeviceInterfaceGUID value in the registry key indicated below. If the device failed to install, that value may be missing. Please note this is the interface 1 (MI_01), interface 2 is used by Nokia for something different.

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_0421&PID_0661&MI_01\7&338e4600&1&0001\Device Parameters]
    "ExtPropDescSemaphore"=dword:00000001
    "DeviceInterfaceGUID"="{26fedc4e-6ac3-4241-9e4d-e3d4b2c5c534}"

    2) Inspect the usbflags\042106610100 key below. The osvc value is the relevant thing to look for, it won’t start with 01 if the device wasn’t recognized correctly:

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\042106610100]
    "osvc"=hex:01,42
    "SkipContainerIdQuery"=hex:01,00,00,00

    The long number, in this case 042106610100 was derived from the Vendor ID (0421), the Product ID (0661) and the revision number (0100) of the device.
    More USBFLAGS info:
    http://msdn.microsoft.com/en-us/library/windows/hardware/jj649944(v=vs.85).aspx

    The correct workaround, if these values are not correct, is to (1) uninstall the devices under “Universal Serial Bus Devices” from Device Manager, (2) remove the key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\042106610100” manually (use that number only if it is the Nokia 920), and then attach the phone again.

    Hope this helps,

    Mark

  • This would seem to suggest that there is a problem with the USB cable, USB controller in your computer and/or the phone itself. Try using different USB ports on your computer. In order to find out if it is your computer, cable, or device, see if a friend can install the tools on their computer (it doesn't need to be SLAT compatible if using a physical phone).

    Can you inspect the Configuration Manager installation (Plug and Play activity) log (c:\Windows\Inf\setupapi.dev), in particular the end, to see what is being reported?

    This is what I have found reported, not really sure what to make of it, apart from the obvious sign that there's a failure. The phone is visible in file explorer and I can view its contents jsut deploying that is the problem.

  • I had a problem earlier getting a connection to a preproduction 920.  Try going into Settings->Date+Time, turn Set Automatically to OFF (if it is ON) and resetting the time manually. See if this helps.

  • No luck unfortunately Mark, I posted on the Nokia developer forums also and the only suggestion they could come up with was to reinstall the WP8 SDK, will this help?

    http://www.developer.nokia.com/Community/Discussion/showthread.php?238433-Unable-to-connect-to-Windows-Phone-8-device&p=906845#post906845

    The Windows Phone 8 connector app works completely fine, just can't use it as a developer device...

    Tuesday, November 20, 2012 6:55 PM
  • Yes it is possible the SDK is in an unusual state. You can try the WP8 SDK Repair option (Control Panel->Programs->Programs and Features) first and see if that helps.

    Do you have another computer that you can install the tools on (or do you have a friend with one)? It doesn't need to meet the SLAT requirement if using a real phone instead of the emulator. The results of the test can help decide what to do next.

  • I have uninstalled and reinstalled the SDK, no luck unfortunately. Still exactly the same error.

    I have installed an app to the device using the same cable from another Windows 8 laptop with no issues.

  • Hi James,

    Since it failed with two different phones, it seems the common denominator is the USB hardware in your computer. Try every USB port available, and if it still fails you might need to use a different computer.  Since you are deploying to a device instead of the emulator, the different computer does not need to be SLAT capable, though it will still require Windows 8.

  • Hi Mark,

    Thanks for getting back to me about this issue, I've temporarily lost access to a device but will let you know how I get on when I've got another,

    Thanks again,

    James

    Tuesday, November 27, 2012 8:11 PM
  • Hi Mark, 

    Great news, I followed your instructions and I discovered:

    1) There was no DeviceInterfaceGUID.

    2) osvc"=hex:01,42 was different

    I found the USBFlag and although I was using an 820 I deleted the key that was very similar (if not the same to the 920 one you wrote above). I then uninstalled the device as you said, plugged in and hey presto - it worked.

    Thanks so much for your help, would never in a million years have worked that out for myself.

The instructions above that Mark has given are the correct fix, if you follow them you shouldn't have any problems at all. Then if you get stuck let me know and I'll try and remember what I did :)

  • I struggled with this issue back in November, and gave up, trading my Windows Phone 8 development for Windows 8 instead.  Now I am back to my Windows Phone still with this same issue.  I was getting the errors that Marks post suggested (no partners) but deleting the registry key and deleting the device from the device manager did not help. 

    What finally did help was I manually added the missing DeviceInterfaceGUID and SkipContainerIdQuery values from Mark's post, restarted Windows Phone IP over USB Transport (IpOverUsbSvc) and now I am working and have managed to deploy an app to my Lumia 920!

    Thanks for the help Mark.

  • Yes!! Mark's solution worked for me also.

    My Windows 8 was able to see the Lumia 820 and mount my device, but I could not deploy to it. 

    In my case I was getting no partner connections found. Like James, there was no DeviceInterfaceGUID in the registry. However, after uninstalling all the drivers in device manager and deleting the specified file in the registry it worked.

    Thanks so much Mark, I was beginning to feel defeated.

    Wednesday, March 13, 2013 2:19 PM
  • These steps helped! Thanks a lot.

    Why does this happen? Mine was a clean installation of windows 8 and a new windows phone 8 device.

  • Hi Mark,

    I was having issues with my HTC 8X and although I had to find the alternate areas of the registry your instructions allowed me to get my device working. For HTC it looks like the Vendor ID is OBB4.  I found the USB device in the device manager and removed it and it re-installed.  As a note I had a hunch mine has issues because the phone kept showing in the device manager with C625a under unknown devices.

    Thank you!

  • I had the same issue (Lumia 920 and Lumia 820 developer device) on my laptop (Sony VAIO VPCF1390X).

    My problem was an old version of my USB host controller driver. I tried updating drivers via the 'Update Driver' button in device manager properties, but it reported that the latest driver was installed. Due to some issues with VMWare USB passthrough, I ended up installing the latest Renesas host controller drivers from the intel web site https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=19880&lang=eng&wapkw=renesas+driver. After installing, i then clicked on 'Update Driver' in the host controller properties, and windows detected and installed a new driver. The new host controller driver is reported as 'Renesas USB 3.0 eXtensible Host Controller - 0096 (Microsoft)'. I think the relevant point is that it's now reported as an xHCI Host Controller.

    Now, IpOverUsbEnum.exe reports the proper output for my phones, the unlock utility succeeded, and I can successfully deploy to the devices. And VMWare USB passthrough succeeds.

  • Hello,

    I would like to know if this topic is related to the explorer of Windows XP where the Nokia Lumia 820 is displayed but we can't display the content of the 2 memory (internal and micro SD) ???

    IF YES , 

    I have the same problem ...and since an update in february and march 2013 ...

    And in this topic, I don't find the way to fix the problem ...or it's not enough clear for me ...

  • Hey everyone having this issue:

    Mine wasn't showing under "portable devices" neither under "Universal serial bus devices", so disconected and reconnected and appeared under "portable devices" in device manager. Deleted and removed device from wherever it was appearing.

    Ran registration tool and it worked!

    Saturday, August 17, 2013 1:27 PM
  • Hello,

    Well, under WiN XP and Seven, the WP8 (Nokia Lumia 820) is visible under the Windows Explorer.

    But, the content is not visible : internal memory and micro_sd card.

    And under SkyDrive, the phone is “locked”.

    Then, I can’t transfer the data directly using USB cable.

    Regards,

    Monday, August 19, 2013 10:58 AM
  • Yeah, all our files are to be stored in their skydrive server for us to access, but the thing is, we can no longer access our precious personal / business files when no internet connection or 3g/4g coverage. Androids can. im sorry

  • Hi Mark,

    I am experiencing the same problem here with my Lumia 920 on Windows 8.1 Pro N, and would appreciate any help you're able to offer.  In summary:

    1.The device does not appear in File Explorer

    2. in Device Manager, I see two entries under 'Universal Serial Bus devices' for 'RM-821|Nokia Lumia 920' where the 'Device status' for each shows 'This device is working properly'.  I also have one entry under 'Other devices' for 'RM-821|Nokia Lumia 920' where the 'Device status' shows, 'The drivers for this device are not installed. (Code 28)'

    3. I have uninstalled the three entries above, restarted the computer, reconnected the phone and all combinations thereof, but the configuration in 2. above is repeated each time.

    4. I have followed your steps above with regard to IpOverUsbEnum.exe but the output is as you've indicated is expected.

    5. I have checked the registry entries and all are as you've suggested they should be.

    6. I have tried a different cable, with the same results

    7. If I try to run the Windows Phone application, it loads then disappears without any information.

    8. I have downloaded the WinUSB driver from Microsoft and installed that (right click, Install) but in Device Manager, that doesn't change the Device status under 'Other devices'

    9. If i try to 'Update driver' for the Device Manager entry under 'Other devices' and point to either 'c:\windows\inf\' or the newly downloaded driver, I get a message to say that no driver was found for the device.

    So, I'm at a loss here - any idea how I might get this sorted out ?

    thanks

  • Hi all.

    Problems here too. Fresh install of Windows 8.1 Lumia Nokia 920 recognized without problems. Visible  in device manager and file explorer. Able to see what files are on my Phone.

    Fresh install of Visual Studio, including Phone SDK. After this install my Phone is still visible in device Manager and File Explorer. My Phone is unlocked and I do have a Developer Licence. In File explorer I now am no longer able to see aything on my Phone, it shows up as empty.

    Deploying a simple app to the Phone will allways fail because of a time out while deploying. Everything runs fine in the emulator in all resolutions.

    Check if the IpOverUSB service was running. There weren't any problems there.

    Next I did a System Restore and checked the status of my Phone in File Explorer. Worked great again!!! So I installed Visual Studio 2013 again, this time without the Windows Phone SDK. Phone was still recognized by FileExplorer and I was still able to see what was on the Phone. Very nice so far.

    Then I installed the Window Phone SDK again. The result was that in File Explorer I could not see the contents of my Phone any more, and again wasn't able to deploy to my Phone. So I switched of the IpOverUSB service. Now in file Explorer I was able to see the files on my Phone again. After switching the service back on again, this didn't wordk anymore. A couple of tries learned that running the IpOverUsb service prevented File Explorer to read the Phone, though it still was listed.

    This was all done whith the latest (final) releases of Windows 8.1 and Visual Studio 2013. I have also tried uninstalling drivers numerous times, resetting my Phone, checking the registry, so just about every solution I've read about, but nothing seems to work.

    Maybe some one with the same problems could verify my problem and steps, especially where the IpOverUSB service is concerned.

  • Mark, similar (kinda) problem.

    Have a Nokia 920. When I have plugged it into PC it never shows up ANYWHERE, not even as an "unknown" device. Have reset/restored the phone, no luck. Portable Devices does not even show up in Device Manager. Nokia is not listed under "Legacy Hardware" under Portable Devices even if looking in "Add Legacy Hardware"......any clues?

  • This works for the S Neo as well, uninstalled the devices under “Universal Serial Bus Devices” and "Portable Devices"

    Then removed the usbflag "045Exxxxxxxxx"(refer to the correct vendor id+product id+revision number)

    Thanks guys great work.

  • WiseOldElf,

    I have this EXACT same problem with a 520 and 1520. Did you find a solution?

  • Try restart your Windows Phone 8. I tried every thing above but still not work.
    I am surprise when I got it fix by restart the phone.

    For Lumia 920, hold power and low volume button for 20 second.
