Actually, it seems .open() succeeds and that the problem is on Node's end cleaning up.

var usb = require('usb');

usb.setDebugLevel(4);

var device = usb.findByIds(0x0eb8, 0xf000);

device.open();

console.log('ok');

device.close();

Probably #100

I´m observing exactly the same issue on Node 4.0.0 with the latest version from master.

Same with Node 4
