    I'm running iTunes 9.0.2 on Windows XP Professional (32-bit). I use MediaMonkey as my default media player of choice, and I either use that to sync music to my iPhone (jailbroken 3.1.2, 2G) directly within the app, or I drag the songs into my iPhone in iTunes from the MediaMonkey window. Randomly, for over 2 weeks, my iPhone has stopped being recognized by my computer.

    Everytime I plug it in, its seen by the computer as "Unknown Device". On top of this, I've had the pre-existing error with iTunes that the registry values for burning CDs is missing and that I should reinstall iTunes. I doubt this is relative to my problem though since it's isolated and my its been there since before this issue. Anyways, I've tried

    - Manually installing the driver (USBAPPL.sys)
    - Uninstalling iTunes with Revo Uninstaller, deleting the iTunes folder in "My Music", and reinstalling
    - Stopping the Apple Mobile Device service and Starting it again
    - Downgrading iTunes after using my 2nd method

    Nothing seems to work, and I cannot figure out what it could be. This is really, really pissing me off. Any ideas?

    Oh, and I haven't installed any additional software that might have caused this. I don't feel like rolling back via System Restore since its been a while.

    Have you installed anything from Cydia that may screw it up?
    I've installed a couple of things that have stopped normal functions such as not being able to delete App Store apps. =/

    I don't think so. Lately I've been using the Rock App because it's faster and it backs up your packages under a username so you can restore them. But I don't think I've added anything. Actually, I've enabled Advanced System Preferences through Winterboard, maybe I changed something? I'll double check, but I doubt there was anything related to my issue.

    EDIT: Nothing.

    I had this problem with a touch. 2 secs lemme find the guide i had...

    You may eventually need to reinstal the firmware. but try these..

    alright....

    1.) reinstalled itunes and the ipod setup (several times)
    2.) tried to hold the menu + center button
    3.) tried to hold the play and center button

    1. Tried Resetting the iPod (press and HOLD the Menu and Center buttons for up to ten seconds) WHILE the iPod is connected to the PC?

    2. Using are USB port on the rear of the tower PC's tower? Front mounted USB ports often don't carry the same amount of "juice" as ones connected directly to the motherboard.

    3. Have you checked to see that your PC has USB 2.0 support?

    Open the Device Manager and expand the tree for the Universal Serial Bus Controllers. Find the Enhanced USB Controller, right-click on it and Uninstall it. Reboot. Give Windows a few minutes to reinstall the device after rebooting. Connect iPod and cross your finger's.



    Thats all i know.

    Yes, well unfortunately neither an iPhone nor iTouch have physical Play, Menu, Rewind, and Fast Forward buttons.

    I know how to restore it, and put it in recovery and DFU mode. The problem is that the driver isn't registering and I cannot choose it from the list when the popup window comes up because it shows up as "Unknown Device" rather than iPhone. My computer doesn't know what the hell it is is the issue.

    I'm not going to unjailbreak it. It happened randomly, I doubt I did anything to cause it, or at least knowingly. On the iPhone-side, everything is fine. I think it has something to do with the computer.

    EDIT: No way. No fucking way. I can't believe it. It was actually the third-party wire I was using. I read it somewhere else and didn't believe it. Now it works with the stock Apple cable.
