webusb-libusb-shim

Experimental libusb-WebUSB shim to enable compiling libusb-based C-programs to Wasm, and have the USB logic "just work".

This is experimental and incomplete, but is sufficiently functional to build unmodified libhackrf and hackrf_transfer to Wasm, run it in a browser, receive IQ to MEMFS, and download the resulting IQ file.

prerequisites

• Emscripten
• Chrome-based browser (note that Ubuntu's Chromium Snap does not have access to USB devices)

build and run

$ git clone https://github.com/marcnewlin/webusb-libusb-shim.git

$ cd webusb-libusb-shim

$ git submodule init && git submodule update

$ make -j

$ ./run-web-server.sh

Navigate to http://127.0.0.1:8000/ in Chrome (or another compatible browser), and press Start.
