USB (Universal Serial Bus) equipment

TL;DR: In this article, the authors proposed a method for achieving a USB combined device suitable for a high-capacity USIM and relates to the technical field of high capacity USIMs. But this method requires a host and a USIM card to be included in the method.

TL;DR: In this article, an automated testing method of simulating inserting and pulling of a USB of a car audio, comprising the following steps: configuring a testing sample; (2) performing connection and configuration, connecting the testing sample in the step A with a USB device and a programmable power supply and performing configuration, and forming a test access; (3) performing voltage control on the USB device by the programmable Power supply, and recording test data of the test sample to form a test report.

TL;DR: In this paper, the authors present a line identification method and device of electronic equipment, which is applied to the process of connecting a port of the electronic equipment and a connector of a corresponding external line, and they make it convenient for the user to conduct blind plugging in a dark environment, and conduct plugging operation in a narrow space.

TL;DR: In this paper, a device identification method, a processor, and an identification system for non-standard devices is presented. And the method includes the steps of determining that a first device is inserted into the interface when a first insertion signal is received, sending a first identification signal to the first device through the first communication channel, detecting that whether a first feedback signal fed back by the first devices is received in preset time, if not, determining the firstdevice as a non-Standard device and switching to the communication with the interface through the second communication channel.
