When I plug my iPhone 6 in to the USB port, iTunes doesn't see it. When I check the phone in the Device Manager the Device Status says "This device is not configured correctly. (Code 1)".
When I try to update the driver either from online or from the Apple Mobile Device Driver on my system, I get "Windows found the driver software for your device but encountered an error while attempting to install. Apple Mobile Device USB Driver. The data is invalid"
I have uninstalled all Apple software and reinstalled iTunes with anti-virus (Avast) protection disabled without success.
Any help will be most appreciated.
