After testing, it can be read directly. But there is no way to read it automatically (there will be security issues).

Answer 2

js doesn’t work, but node does. Run in the background, check to see if the USB disk is there every once in a while, and operate it if it is. This is the simplest and most crude method.

Answer 3

js is ok, but it depends on the environment. It won’t work in the browser anyway
