Yes, I believe it has been implemented for bangle.js, just not as a module. See:
https://github.com/espruino/BangleApps/blob/master/apps/boot/hid_info.txt
And it gets used like this:
https://github.com/espruino/BangleApps/blob/master/apps/hidjoystick/app.js#L11
So you should just be able to piece those two bits together - let me know if you need a hand though!
