US 2020/0394149 A1 · DRP DETERMINING SYSTEM AND DRP DETERMINING METHOD USING THE SAME

Abstract

A DRP determining method is provided. The method includes the following steps. Firstly, a first DRP electronic device and a second DRP electronic device are connected by a USB Type-C line. Then, the first DRP electronic device is set to one of a host and a device. Then, the second DRP electronic device is set to one of the host and the device. When the connection between the first DRP electronic device and the second DRP electronic device is disconnected and then re-connected, at least one of the first DRP electronic device and the second DRP electronic device is set to the other one of the host and the device.
