Hi guys,

So i get the issue that when i plug my iPhone 3G into the PC via USB it shows up in My Computer and Device Manager but if i load iTunes then iTunes freezes for a few minutes and then doesnt show the iPhone at all. iTunes becomes responsive if i unplug the iphone during the freeze but plugging it in again results in the same freeze.

The weirdest thing about it is the phone will occasionally show in iTunes, often when a new iOS update is available. This has been happening with two different iPhones, doesnt happen with iPod. It works fine in Windows XP.

I have tried multiple full uninstalls of everything apple related - itunes, quicktime, bonjour, update service and then manually deleting anything with those in the folder name followed by CCleaner registry cleanup, deleting iphone USB driver and reinstalling.


I am definitely using the 64 bit .exe, i have tried running as administrator and not, running in XP SP3 compatibility mode and not. I dont change what media is on the phone very often but i like to be able to do it (and backup regularly) when i want to not when my PC feels like it!

I REALLY DONT WANT to have to format windows although i think i'm out of options - unless anyone here can help??!?!!

""i had a similar problem.

running windows 7 ultimate 64 bit. and itunes on my computer recognized my iphone as being plugged in. but windows 7 did not. it registered it as a mtp device under device manager. disabling me from from getting pictures off my iphone.

what helped me was i uninstalled the mtp usb portable device in my device manager, which Windows 7 apparently believed was my iphone. then uninstalled all apple softwares installed including apple device manager, uninstalled quicktime and itunes, restarted my computer as requested by the itunes uninstaller and upon restart without any apple software on there. my windows 7 immediately recognized my iphone as being an apple iphone (finally!).

now i'm going to install itunes again to see if this stays that way.

What seems to be the issue is any photos on your iphone's camera roll that were not taken by your iPhone. Transfer the photos off your iPhone, and delete the old MPT USB Device (failed install) from your device manager, then reconnect your iPhone. I think your issue will magically be fixed, and we all know magic is what you need these days, or atleast some good ganja.""
 
I had this issue. After some googling I found that my problem was a compatability issue with the P55 chipset. As you describe, sometimes itunes would find the iphone, but not often. A workaround was to disable 'c-state' in the BIOS. In fact, googling 'c-state' shows mostly itunes/P55 pages. I checked the Asus site and found that a motherboard BIOS update was available. Within the release notes it said it fixed compatability issues with some USB devices. I flashed the motherboard and it had been working 100% for months now, not one single issue.
