<s>[INST] explain WebUSB in simple terms [/INST] WebUSB is a technology that allows websites to access and interact with USB devices connected to a user's computer or mobile device, directly from a web browser. This means that instead of requiring users to download special drivers or software, websites can communicate with USB devices through the browser.

For example, a website could use WebUSB to control a printer, read data from a temperature sensor, or even control a drone. With WebUSB, the website can directly communicate with the USB device, without needing any special software or drivers installed on the user's device.

However, it's worth noting that WebUSB is still a relatively new technology, and not all devices are compatible with it. Additionally, due to security concerns, WebUSB is only available on HTTPS websites, which means that websites need to have a valid SSL certificate to use WebUSB. </s>
