You generally can't directly access low-level operating system services like /dev from a browser for security reasons. Some services may be wrapped through HTML5 APIs (e.g. WebGL, WebAudio, WebRTC etc) and emscripten uses those to emulate common low level APIs so that a lot of code can compile, but I guess you're out of lack for directly accessing USB, and especially /dev, which non-portable Linux concept.
Googling for 'HTML5 USB' might provide more clues but I wouldn't get my hopes up :) Cheers, -Floh. Am Mittwoch, 30.
