Can't find my iPhone 5c on iTunes 12.3.3 on Windows 7?

I plug in my phone, it charges but can't be discovered in iTunes In order to sync. I've tried finding the device in device manager and it's nowhere to be seen. I've recently upgraded my iTunes and Windows software from vista to 7 and 12.1.3 to 12.3.3 and this still doesn't work. Thought it could be the cable so I bought a new Apple official one and still no luck. Any ideas?

Try a different USB port. Make sure the drivers are current.
