If you’ve recently upgraded or purchased a new machine with Windows 7 installed and you’re an iPhone user you might have encountered the annoying (quite irritating actually) 0xE8000065 error when trying to sync your iPhone with iTunes.
More often than not, the phone connects and everything seems fine, but iTunes can’t connect to it. You’re not alone. Many users have reported this problem. The problem seems to stem from the Intel P55 chipset, but not always.
Solving the 0xE8000065 “unknown error”.
The solution that seems to be working for most people is to disable Windows 7 USB power management. In Windows 7, the operating system tries to control devices and “turn them off” when not used. This feature is not necessary and it seems the Windows 7 P55 chipset drivers are faulty so it won’t work anyway. The solution is simply to turn off that feature.
Disable USB Power Management in Windows 7
First, click the start button, and type devmgmt.msc followed by the enter key.
Under Universal Serial Bus Controllers, you will find one or more USB Root Hub devices. You’ll need to follow these steps for each one listed (unless you know the exact one your iPhone is connected to). Right click the USB Root Hub device and then click properties.
Under the Advanced tab uncheck the box next to Allow the computer to turn off this device to save power. Click OK and close everything. Reboot your computer.
From what we’ve seen, this solves the 0xE8000065 “unknown error” on about 90% of the machines out there.

I had this same error and every iphone I tried generated this error. Turned out that my power supply was the problem. The problem resolved itself after I changed power supplies. The problem pw actually failed, prompting me to replace. I replaced and Enermax 650watt with an Antec 650watt. The Enermax had modular cables, and was the first Enermax I’ve owned that failed.
Try swapping out power supplies – worked for me.
