Recently, two former Google engineers, Reilly Grant and Ken Rockot, made a program interface, and the hardware devices will not need to be installed later.
Recently, they submitted a draft to the World Wide Web Consortium (W3C) to allow USB devices, such as keyboards and IoT devices, to access the network directly. The name of this interface is called the WebUSB API (Application Programming Interface). With this method, hardware devices can be directly controlled by the web.
The two developers said that today we usually have only two requirements for devices connected to the computer: the computer can find it and it works. Most devices such as mice, keyboards, cameras, etc. because they have a standard set of drivers. However, with the development of the Internet of Things technology, more and more new hardware devices have emerged, but they lack such a standard, which makes it impossible for developers to directly control them through the web, which requires additional software installation. So they use this new approach to streamline the process.
For example, if someone wants to print an object using a 3D printer, just press CTRL+ALT+P (the Windows system print command) on the keyboard and the printer will execute the command. Previously, developers couldn't use the web side to do direct operations on 3D printers, but instead needed to install a series of complex debugs or drivers. The WebUSB API simplifies this process.
In addition to providing a more convenient network portal for IoT devices, this new interface is also more secure. Originally connected to the USB interface, the information exchange between the computer and the hardware device is connected. However, after the new interface is used, the communication becomes more unidirectional, and the web terminal can directly execute the operation command on the network, but the webpage cannot obtain the user through the USB device. Other data information, which guarantees user data security.
The good news is that the new interface also has some compatibility, which means you have old USB devices that you can use. Although the WebUSB API is still in an unofficial state, you can find the WebUSB API source code on GitHub.
