Question

USB

Hello everyone,
Who came across, please tell me the fastest way to set up a cross-platform way to communicate with USB from a browser?
The task is to read and write data from the browser to a USB drive.

Answer 1

Legally, without installing third-party software on the user's computer, this is impossible.
Viruses do this illegally, through vulnerabilities in browsers, for example.
