I've encountered the following problem on my MIUI device:
After turning off both MTP and PTP connections from the notification bar drop down menu and reconnecting the device to the PC this menu does not appear anymore. Since both MTP and PTP are turned off the PC doesn't see the device. MTP and PTP can't be turned back since USB connection settings are not accessible from the phone's Settings.

This app simply opens the USB connection settings so MTP or PTP can be turned back on.
