Q: Why does my iPhone 6 not show up in my computer when it's plugged in with the USB cable?

Because you already have 5 IOS devices registered ! Delete one, than try again.

You already have 5 IOS devices registered. This is the limit. Delete one, than try again.

See this support document if your device is not being recognized by the computer. iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support

It seems as though you might, but the only time that it appears in Computer is if there are photos in the Camera Roll. Otherwise, it will not appear. You do not have access to the file system, so there is no reason for it to be in Computer. If you do have photos in the camera roll, then you may need to go back to that support document that I linked, and take a look at information about the Apple Mobile Device Driver, and USB driver.

Worse case scenario is to remove iTunes and reinstall it. If you have to do that to recover drivers for Windows, then make sure you do it exactly as this support document outlines. Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support

If you vary from this method, you can create more problems. Good luck.

Franz, how do I delete a device?

I had the same problem on my Iphone 5. It drove me crazy. I tried reinstalling ITunes and my apple mobile device driver, but nothing solved the problem. I was able to detect my iphone in windows if I went to control panel, then programs and features, found apple mobile device, right click, then click repair. This would allow windows explorer to detect my iphone, but I had to do this every time and it also drove me crazy, After trying everything I could think of, I decided to try and uninstall a program called expresso media. I am not sure where it even came from, but walla, once I uninstalled it my iphone shows up in explorer and iTunes just like it should. Simple but frustrating. Good luck,

   p.s. Also the posts are correct when they tell you that youre iphone will not show up in windows explorer if youre camera roll is empty.

Your iPad should be recognized as a camera if you start your image capture or camera application on the computer. Your iPad will also appear in iTunes on your computer. Your iPad will not appear like a connected hard drive.

I had this problem too, and finally found a fix.

I tried all the fixes and driver updates (to no avail) but what worked for me was to go to Control Panel>Devices and Printers. The Apple iPhone was there but appeared under "Unspecified."  I right-clicked and selected Troubleshoot. Apparently "the device was not enabled" so I selected the "enable device" fix. The phone/pics appeared as a folder in Windows immediately.  I have no idea why the phone gets "disabled" every now and then but this works every time.

I have a PC, fwiw.  Good luck.
