There are 3 protocols when you connect your Android phone to computer. They are: MTP, PTP and USB Mass Storage. If your device is not detected, please try with another two modes. As to the differences of these transfer protocols, you can refer to the following:
MTP: MTP stands for "Media Transfer Protocol." When you choose this mode, your Android device will prompt to your computer as a "media device." The media transfer protocol is a standardized protocol for transferring audio files to digital music players via Windows Media Player or similar applications.
PTP: PTP is short for "Picture Transfer Protocol." When you choose this protocol, your device will prompt as a digital camera.
USB Mass Storage: USB mass storage is the standard protocol used by flash drives, external hard drives, SD cards, and other USB storage devices. Under this mode, the external drives will become completely available to the computer, just as if it were an internal drive.
Android system has a developing function named USB debugging mode, with which you can transfer files between Android device and computer, install third-party APPs on Android devices, read log data and do other operations to your device.

After you root your phone successfully, a rooting management App will be installed automatically in your phone. This App (Super User, Super SU, KingUser, etc.) is different according to different rooting software. But they all do similar functions to manage your phone's permission. Meanwhile, FoneGo, one App from our software will request the permission to your phone for scanning your deleted data on phone. At this point, if there is reminder showing the scanning process is not successful, then your phone may get a default setting to reject the request from FoneGo. So you need to grant FoneGo permission to continue the following operations. The details are as following,
