Description

Automatic mapping of updated computer adapters

technical field

The invention relates to a computer, in particular to a computer switching device for automatic mapping update.

Background technique

When a computer cannot meet the needs of use due to work or replacement, adding a computer or continuing to use the replaced machine is the most common way to think of it. In the case of limited space and low budget, these ideas could not be realized in the past, but with the rapid development of today's electronic information technology, whether it is to add a new computer or continue to use the old machine, it only needs to be purchased through an additional computer. The serial connection of the computer switch (KVM) can allow two (or more) computer hosts to share a keyboard, mouse, screen, and even speakers, microphones and various external peripheral electronic devices. The operator can not only have a wider working space to increase work efficiency, but also greatly save the cost of purchasing additional peripheral equipment.

The so-called computer switcher (KVM) is the switcher of the keyboard (Keyboard), monitor (Video) and mouse (Mouse), which allows users to use the same set of keyboards, monitors and mice to simultaneously operate on multiple computers. Switching the operation screen not only simplifies the operating equipment of multiple computer environments, but also allows users to manage different computers or servers simultaneously without interrupting the work of the original computer through fast switching, thus improving the user experience. convenience.

However, general commercially available universal serial bus (USB) type computer switchers cannot cover all types of USB devices, resulting in the use of multi-function mice, keyboards, joysticks, touch screens or other USB devices. Computer interface devices (HID) often appear incompatibility and connection situations, because the enumeration, report analysis or other structural configuration of this kind of USB device is simulated and converted into the preset computer interface established format, so it cannot be applied to all Types and types of USB devices, and general computer switchers need to pass through a hub (USB Hub) to connect USB devices other than mouse and keyboard. Therefore, when encountering the above problems, in addition to replacing compatible USB devices, some computers The switch uses an updated version of the control program (adding emulation and conversion content) to solve the problem, but neither of them can completely solve the problem of USB device incompatibility. Great inconvenience.
