How to fix my apple USB Driver?

My iPhone has has some issues getting it to charge and stuff, I fix the problem and now it charges, the problem now is that I tried to update my iTunes media, I connected it to my laptop and it didn't recognize the device, it didn't charge nor appear on my laptop or iTunes, the USB port works fine and also the adapter, I uninstalled the apple USB Driver and when I connected the iPhone again it did appear on my laptop but I couldn't check what was on it also it didn't appear with the name it had just Apple iPhone, and when I go to the internal storage nothing appears on it normally there's the folder with the photos but when I open iTunes my iPhone is not in there. How do I reinstall the apple USB Drive since I don't have it anymore? Do I have to delete my whole iTunes and reinstall everything again or can I just install the drive? If so how?

Your iPhone may not be the problem…

Go to any store that sells Apple Mobile Devices, and ask them to test your USB Cable.

My guess is: it is defective.
