ITunes could not connect to this iPhone because an unknown error occurred

Well, there’s a lot of information that you left out regarding your problem. For now, I will try to provide you with a number of solutions that may work. Please note that some might not work as it might not be designed for your system. Anyways, here are a number of solutions that you might want to try:

• Make sure that your iTunes software and your Operating System is updated.

• Try Uninstalling iTunes completely out of the system. When I say completely uninstall the program, I mean everything that is connected with iTunes namely: (Bonjour Service, iTunes, QuickTime, and even the drivers that came from Apple). Just go to control panel and click on programs and features, and uninstall everything that’s from Apple. Alternatively, you may use a program like Revo Uninstaller to uninstall iTunes.

• Reset your iPhone back to factory default. After doing so, you may try to sync your iPhone again with your iTunes.

• Since you are using a laptop, I can only imagine that it has limited USB ports, have you tried to connect your iPhone to different USB ports on the laptop?

• You might also want to check Windows Media Player if its giving you some conflicts with your iPhone. To do so, you need to completely turn off all the features of Windows Media Player. You can do this by going to Control Panel > Programs > Turn On and Off Windows Features (Which is located on the left hand side of the window) > Uncheck Media Features. Then try plugging in our iPhone and see if it’ll work.

• In some cases, it is a problem with the USB device driver. Check and see if you have the updated version of the device driver. Since you are using a laptop, it is easier to check. Just go the manufacturer’s website of your laptop and download the latest Chipset / motherboard driver and install.

• Also, iTunes uses a certain driver that’s developed by gear software. Try installing the latest version that can be downloaded from this website. http://www.gearsoftware.com/support/drivers.php.

• If you have an external USB hub available, try using it. Connect your external USB hub to any of the USB ports on the laptop and then connect your iPhone to that USB hub.

• Enable the C-State for the processor. This is a mode that enables the processor to save power on different cores. It more like a built-on monitoring software in the BIOS, and it sometimes affects programs on a system. To enable the C-State you need to boot into the BIOS Set Up screen of your system. Getting to the BIOS screen is different for each manufacturer, but you might try pressing “ESC”, “F2” or even “F12” right after you turn the power on.

If all these fail, then you might want to take your iPhone to an Apple Store and have them check it for any defects. Good Luck.
