In my case Faced the Same Issue with My Redmi 3s PRIME and I can't able to enable the Install Via USB and it asks to connect Network So I tried the Following Method and luckily it works...!!

1. Open Inbuilt Securit App.

2. Click On Optimize. (While Scanning, It Disables the Developer Option )

3. Now Open Settings->About Phone-> Tap On MIUI Version to Enable the Developer Option

4. Open Additional Settings -> Developer Options.

5. Now Re-enable the USB Debugging it automatically enables the Install Via USB

6. In Android Studio Disable Instant Run Settings>Build, Execution, Deployment>Instant Run

7. Now Run the App with Android Studio.
