When two hosts are connected, it sets up a screen share and USB-C peer-to-peer network to allow drag and drop files, mouse and keyboard sharing.

Who is the ATEN US3342 4-port USB-C Gen 2 sharing switch for?
OK, it has a specific market – anyone that has two host devices and wants to share peripherals.
For example, at my office, a few people have a Windows 10 laptop and a MacBook because they need to access different software. Data transfer is via a ‘sneaker-net’ (it does not interfere with any LAN). This breaks down the barrier, and they can plug in a shared external drive, mouse, keyboard, scanner, printer etc.
But I see a great need for programmers, developers, system administrators, PC repair technicians, and content creators to enhance the efficiency of dual-system operations.
