2. Integrate the Attached Device with Your Web Application: Once the USB device is attached to the client machine via USB/IP, it will be accessible to any software running on that machine, including a web application. The web application can then communicate with the device using standard USB communication libraries (e.g., libusb for C/C++, pyusb for Python) just as if the device were directly connected to the client machine. The web server (e.g., Apache, Nginx) and the application framework (e.g., Node.js, Django) on the client machine handle the web interface, while the application code uses the local USB device.
3. Alternative: Use a Local Service (e.g., a Web API): Instead of attaching the device to the web server machine, you can create a separate local service (a daemon or a small application) on the server that communicates directly with the USB device. This service can then expose a simple HTTP API (e.g., using a lightweight framework like Flask or Express) that the web application can call to send commands to or receive data from the USB device. This approach keeps the USB device connection confined to the server and uses standard web protocols for communication.
In summary, the most practical approach is to use USB/IP to make the USB device appear as a local device on the machine hosting the web application, allowing the application to interact with it directly through standard USB libraries.
