I have recently upgraded iTunes to 8.2 (on MacPro Leopard) and since the upgrade the USB will not work on any iPhones or iPods, literally like nothing has been plugged in, but is fine with keyboard mouse etc.

Have tried different cables, all ports, restarting devices and mac. Also tried plugging iPhone/iPods to MacBook (Leopard) and a MacPro running Tiger and all is well.

Any ideas?


Mac OS X (10.5.7), iPhone 3G

    Same here. Updated to ITunes 8.2 on iMac (Tiger). ITunes will not recognize, charge, or sync an iPod Touch, but WILL recognize, charge, and sync an older iPod Nano.

    Thanks for any clues.

    Does the issue persist after Reinstalling iTunes and/or the Apple Mobile Device Service?

    I experienced the same problem after upgrading to iTunes 8.2.
    I rebooted the iphone itself and now itunes recognizes it.
    For some reason I had to reboot the phone twice before it was recognized.

    Appreciation to JASON for this help.

    Obviously I had the same problem, which is why I came here....

    After repeated rebooting of both iPhone (original) and MacBookPro (Sys 10.4.11) after each time (also repeatedly) I reinstalled iTunes, following these steps made it work!!!

    The only thing is that, when I connected the iPhone, the the Summary screen did not appear as it automatically did in the past (I have "Automatic Sync" unchecked). However, by clicking on the iPhone icon in the connection bar down the left side of the screen, that got the summary screen to appear and I was able to complete a normal sync, FINALLY!

    I had the same problem. Since I just had just upgraded to iTunes I tried removing only the AppleMobileDeviceSupport.pkg and then I downloaded and re-installed/upgraded iTunes. That worked great without needing a restart.

    I'm experiencing this problem since this morning.

    If I plug in my iPhone using the USB cable he won't show up on my Macbook Pro. If I connect him to the PC (using the same cable) he shows up instantly.
    Also, when the iPhone is turned off and I plug it in the MBP using the USB he will switch on, shortly show the "charging" icon which will dissapear within 2 seconds. This also happens when I power on the MBP.

    What I've already tried:
    - Reboot the iPhone
    - Reboot the Mac
    - Reinstall iTunes (removing iTunes and the AppleMobileDeviceSupport.pkg)
    - Check USB Connections (every other device works fine)

    Thanks for the resolution, Jason. Worked a treat; just had to use my password for my touch the first time, but have since tried is a few more times and it's back to normal.

    Just one point for Apple; I'm in Sydney, Australia and the local apple website (apple.com.au) still has iTunes 8.1 for download. This problem eventuated as part of weekly software update I've set my Mac to do. I would expect that all regions would have the same software versions being rolled out at the same time. I had to download the software from the US.

    Nearly the problem here, every other device (like ipod nano, external USB-Drive for Time Machine, keyboard, mouse etc) works and syncs, only my iphone (1st gen) is not even recognized by itunes (latest version). I restarted both (phone and mac) several times, completely deleted and reinstalled itunes even more often, also the ituneshelper and itunesmobiledevices. Hopefully there will be a solution soon.

    My Iphone 3G also not found or syncing to iTunes. Problem evident since doing iTunes 8.2 & iPhone 3.0 update. I Took MacBook & iPhone to Genius Bar in Sydney & Genius reinstalled iTunes & carried out corrective actions suggested above with no success. iPhone was faulted & replaced. Problem fixed,
    synced for 2 days and now iPhone not syncing again. Oh well, off to Genius Bar again.
