Where is the new Martha usb interface?

The new Martha usb interface goes deep into the central control armrest box.

Universal serial bus:

Universal serial bus is a serial bus standard and a technical specification for input and output interfaces. Widely used in personal computers, mobile devices and other information and communication products, and extended to photographic equipment, digital television, game consoles and other related fields. The latest generation is USB4, with a transmission speed of 40Gbit/s, a three-stage voltage of 5V/ 12V/20V and a maximum power supply of 100W. The new TypeC interface allows blind plug-in and plug-in.

USB function:

USB is an external bus standard, which is used to standardize the connection and communication between computers and external devices. USB interface has hot plug function. USB interface can connect various peripherals, such as mouse and keyboard. USB was jointly launched by Intel and other companies at the end of 1996. It has successfully replaced serial port and parallel port and become an indispensable interface between computers and a large number of intelligent devices.

Version:

After years of development, the USB version has now developed to version 3. 1. For most engineers, the main obstacle to developing USB2.0 interface products lies in: facing the complex USB2.0 protocol, writing USB device drivers themselves and being familiar with single chip microcomputer programming. This requires not only considerable VC programming experience, but also hardware (firmware) programs that can write USB interfaces. So most people give up developing their own USB products.
