A new USB feature for Windows Phone 8.1 has been revealed in a simple Bing search. Found in our forums by Manikanta R., the trick brings up a hidden USB menu that allows you to enable two new features, including ‘Ask me before using USB data connection’ and ‘Notify me when I connect to a slower charger’. Indeed, we can confirm from our unsanctioned ‘early look’ at Windows Phone 8.1 using a developer device, that these USB options were there under the Settings menu. They were removed (or hidden) in the reviewer build that we received and also in the Preview release.

It’s not clear why this feature was hidden, though if we had to guess it has to do with specific OEM hardware needing to be configured to fully leverage it. That is, we should expect this feature to return once official updates with the corresponding firmware begins to rollout in the coming weeks.
