1. Under this circumstance, please click the drop-down list and switch to another connection mode, then reconnect the device. There are three connection modes, MTP, PTP and USB Mass Storage. Following is the introduction to these three modes.
MTP: MTP stands for "Media Transfer Protocol." When Android uses this protocol, it appears to the computer as a "media device." The media transfer protocol was widely promoted as a standardized protocol for transferring audio files to digital music players using Windows Media Player and similar applications.
PTP: PTP stands for "Picture Transfer Protocol." When Android uses this protocol, it appears to the computer 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. The drive makes itself completely available to the computer, just as if it were an internal drive.
