Description

Hi,
I've successfully communicated and controlled my USB device within a browser using Emscripten + libusb (compiled into a static library by Emscripten).
Most of code (communication and control) is written in C, and Emscripten compiles it into JavaScript and wasm.

I am specifically concerned about the WebUSB bridging, as Emscripten provides a built-in layer for libusb, which SwiftWasm might lack.

Is it possible to convert this communication and control C code to Swift using Swift SDKs for WebAssembly?

Browser communicate with USB Device?
`My Swift code` + `Swift SDKs for WebAssembly` + `Emscripten libusb static library`
