USB over Network is a software that can share and access USB devices through the local network or the Internet. It is divided into server and client. The server is installed on the computer that is actually connected to the USB device, and the client is installed on the computer that needs to access these devices remotely. This software supports Windows, Linux, and macOS systems and adopts USB virtualization technology to achieve remote access to various USB devices. It does not require the installation of USB device drivers on the server side, ensuring data security and providing flexible sharing rules.
