In the development process of the device, it usually involves debugging of the USB function (if it is a terminal device, it also usually involves the function of USB charging), and in the debugging (debug), it is usually determined whether the USB charging function is normal by acquiring signal waveforms of two data pins.

The common practice of the debugging personnel is to disassemble the machine, open the shell of the terminal equipment, then weld leads on signal points corresponding to the data pins on the circuit board, fly the leads, connect the flying leads with the debugging equipment, and grasp the waveforms of D-, D+ signals in the debugging process. This approach has the following drawbacks:

1. irreversible damage is caused to the terminal equipment, the disassembly machine and the welding lead can damage the shell and the circuit board of the terminal equipment, and particularly, the risk of thermal damage to other components around the welding point exists in the flying lead process.

2. The disassembly can lead to the exposure of the internal structure of the terminal equipment, and the safety risk of information leakage exists.
