Background technique

With the development of personal computers, the interface cards in the computer casings have plug-and-play devices, which eliminates cumbersome adjustments. However, the human-machine interface system outside the computer case is extremely chaotic. From the keyboard socket, the PS2 serial port for the mouse, the 25-pin serial port for the modem, and the parallel port for the printer, etc., it is really difficult to organize the computer. of a nightmare.

In order to solve this problem, at the end of 1994, the industry proposed the idea of USB (Universal Serial Bus, i.e. universal serial interface). The so-called USB uses a structure called Tiered Star topology, which looks like a big tree, and grows out from the USB controller (Host) behind the motherboard as the root. If only one USB device (Device) is connected, the USB controller can directly operate the USB device through the cable. If multiple USB devices are to be connected at one time, there must be a hub (HUB) between the controller and the devices. Sometimes when there are too many devices to be connected, there will be a situation where a hub is followed by a hub. Since the number of devices that can be connected to the USB can be as high as 127, basically as long as the bandwidth permits, the entire computer only needs to have a USB controller, and then expand through the hub to handle all peripheral circuits, which can be said to be greatly improved. It greatly simplifies the human-machine interface system outside the computer case.

Due to the limited speed of the early USB, the peripheral circuits of the PC were more focused on the application level, including the mouse, keyboard, scanner, etc. However, with the emergence of USB2.0, this situation has gradually changed. In some consumer electronics products that require high bandwidth, such as mobile phones, personal data assistants (PDAs), digital cameras, and digital video recorders, USB is also used as the connection port. The product. It can be said that the application level of USB products has been greatly improved.

Usually, these consumer electronic products transmit data with external electronic devices by assembling a USB female connector therein. If the external electronic device is only provided with a USB female connector, the data transmission between the two must be completed by means of a USB adapter device, which makes the operation of these consumer electronic products inconvenient and difficult for users. difficulty.
