Q: itunes won't recognise any of my devices. "Trust this computer" option isn't coming up. Instead, "do you allow this device to access..." comes up. What's happening?

This may help:

If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support

Try the following:

1. Open Control Panel > Device Manager
2. Plug in your device
3. Locate Universal Serial Bus Controllers > Apple Mobile Device USB Driver.
   It is also possible the device may show under Imaging Devices, Portable Devices or Other Devices or as an MTB USB Device.
4. Right-click and select Update Driver Software...
5. Click Browse my computer for driver software
6. Browse to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers or
                   C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers
7. Click Let me pick from a list of device drivers on my computer
8. Click Apple Mobile Device USB Driver
9. Click Next, then Close and exit Device Manager

Or try iPhone, iPad, or iPod not recognized in iTunes for Windows - Apple Support

Failing that try a full tear down and rebuild of iTunes as set out in Troubleshooting issues with iTunes for Windows updates.

I am having the same issues... I completed the same processes/suggestions as above and no luck. Do you have any other suggestions.

Try rolling back to the last build of iTunes that worked for you. See iTunes installers for download links. If you're rolling back from 12.3.3.17 to 12.3.2.35, for example, then you'll also need to roll back the database in the way described in Empty/corrupt iTunes library after upgrade/crash. The tip includes suggestions for reintroducing any recent purchases so at worst you lose a few playcounts and/or a recently created playlist.

Didn't help. I'm having the same problem and it's extremely frustrating. Not to mention after following all of the two-step verification steps, I went to iTunes to download music each time I thought it worked. Now I've racked up $30 worth of iTune charges for music that never downloaded.

This sounds like a different issue. Purchases normally download automatically when you make them, otherwise see Download your past purchases - Apple Support.
