iPhone keeps reconnecting

[dnice]

I recently bought 16 gb Apple iPhone, When i connect iphone to computer it repeatedly reconnect, i tried to connect it with another usb cable but it gives same problem. This happen when i open any application or open music library. I've reinstalled iTunes but to no avail. Does anyone know what causes this issue and how to fix it?Any help will be extremely appreciated.

Is the cable plugged directly in to a USB port or in to a USB hub?Sounds like either a faulty dock or a faulty iPhone. I assume you reset the phone to see if that would fix it?

• On the Start menu, click Control Panel.
• In Control Panel, open Administrative Tools. Note: If you don't see Administrative Tools, look at the left column in Control Panel for a link that says, "Switch to Classic View," and click it.
• Double click the Computer Management shortcut.
• In the left column, click on Device Manager.
• In the right column, click the plus icon next to Universal Serial Bus controllers to expand this selection.
• Right click on "USB 2.0 Enhanced Host Controller" and choose Disable.

Try check and uncheck the box under "disable automatic syncing for all iPhones". Try Connecting and disconnecting it from your computer. Unplug iphone from system and Reboot your system.
