iPhone 3GS shows in iTunes, but not Windows Explorer

Hi Experts,

I am experiencing a problem which has recently come to light. My iPhone 3GS was having serious driver issues, where the 3GS wouldn't even communicate with iTunes, OR charge. However, after hours of attempting to repair the driver in device manager, I ran a system restore.

I have now got iTunes communicating with the phone successfully, and it is also charging... However, I am getting the 'Device Driver Software Was Not Successfully Instaled' error. I do not have my iPhone showing up in My Computer, and need this to regularly copy pics and vids from my phone.

I have also noticed there is still an issue with the iPhone in device manager, EVEN THOUGH iTunes is still working with it.

Please see the screen shots below. Error on connecting 3GS Screenshot, showing iTunes, My Computer, and Device Manager

Please take note, iPhone works fine on other machines, and has worked on this machine of mine fine in the past.


Just to throw a spanner in the works, I am also having an issue which must be related, when I plug in a 4GB flash storage, I get the sound you get when you insert a device, but seconds later, get the error chime windows gives you when there is something wrong with the device..... BUT I can use the USB Pen fine, see the scren shot 'Pen drive error'

I cannot really afford to reinstall Windows and would ideally like a solution, perhaps its a registry fault?

    It looks to me (based on your screenshot and the phone not mapping) that your Data drive d: is throwing a wrench in the system. Open up disk management and see if the phone's partition is listed. It's most likely attempting to map as E and not being able to because the CD rom has to take that letter. Find the partition, right click, and choose change drive letter. Then pick an open drive letter. Looks to me like the other usb device is a seperate issue. Has that device worked on other machines of the same OS?

    Hi tfenner,

    The phone's partition is not even listed at all in disk management, however it is in iTunes, Also, the USB pen works fine on another machine. Strange, I think there is some serious damage somewhere in my registry, don't know that though.

    Ok. After some searching I've found a thread that may help. There are several fixes listed. Give these a try....

    1.Update the driver by expanding 'Portable Devices' from the list, right click Apple iPhone/iPhone and select 'Update Driver Software'. Then select 'Browse My computer...'
    C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers - then hit 'Next'.
    Now detected.

    2.If using a 64-bit version of Windows Vista or Windows 7, type C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers in the "Search for driver software in this location" field when updating the driver.
    iPhone or iPod is not recognized properly by computer when USB drivers are not installed properly or are out of date
    If above does not work then right click on the iTunes shortcut and select properties. Click the compatibility tab and check the "Run this program in compatibility mode" check box. From the drop down menu choose choose Vista service pack 2 and then click Apply. Now double click the iTunes setup.

    3.I had that problem too! the solution that i found to it was to disable internet tethering on your device, and everything worked fine for me

    4.My solution was that after windows madia player 12 installation, my Windows 7 64bit edition finally see my iPhone as device...!!!

    Hi thanks tfenner,

    I have been  through  these suggestions,  firstly, I'm using x64 Win7, and no such directory exists " C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers"

    Had a look around in the Apple installation folders.

    Another one, Windows Media Player 12 is built  into windows 7, cannot download/install it.

    The suggestion which says, change to compatability mode, then run iTunes set up; I got confused here, changing the compatabiility on the allready installed iTunes, then running the SETUP again :S is that right, what would this do? Surely it means to change compatability on the iTunes setup, not the iTunes shortcut?

    Had a read through the links attached, Tethering is not on, on my 3GS either.

    Mine is working on an iphone4 running Win7 x64. Lets compare your drivers to mine. I found the driver files here...
    "C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers"

    Have you upadated your itunes application recently?

    Hi tfenner

    I compared my drivers in  the C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers directory, which appear exactly the same. I downloaded the latest iTunes x64 installer, and ran it, uninstalled and reinstalled iTunes.
    Then attempted to point the MTP USB Device to the drivers in the folder discussed, however I just get a message which says 'The best driver software for your device is already installed'
