iPhones not playing nice with Win7, P55 systems

— 8:19 AM on November 3, 2009

Being an early adopter isn't always all sunshine and kittens. Some folks have found that out the hard way after trying to sync their iPhones on brand-new Lynnfield PCs running Windows 7. As The Register reports, those users have piled complaints into a six-page thread on Apple's discussion forums, all saying iTunes simply refuses to recognize their precious devices.

Plugging in an iPhone allegedly causes the software to throw up an unhelpful error message: "iTunes could not connect to this iPhone because of an unknown error occurred (0xE8000065)." When the device is unplugged, Windows bemoans a failed MTP USB driver installation. Everyone who's complained so far looks to have similar systems—Core i5 or i7-800 processors, P55 motherboards, and Windows 7.

Further posts suggest the problem may have to do with USB power management, but nobody is taking the fall or providing a straightforward solution just yet. An Apple staffer posted in the thread asking users to e-mail him with additional details, such as motherboard models, BIOS versions, iPhone models, etc. In a separate report, PC World got word from an Intel spokesman that the chipmaker is "investigating the issue and believes it is a BIOS or system configuration issue."

The Register cites similar "we're looking into it"-type responses from Asus, Gigabyte, and Microsoft. In the meantime, some users have reported success changing Windows 7's USB power management settings or downgrading iTunes, but the safest bet is probably to sync from another PC.
