if usb subprocess crashes, the interface does not reset correctly

[ddavidebor]

The interface does not reset correctly if subprocess crashes, the loader mouse pointer spins indefinetly and the UI is greyed out

  usb.on('message',(data)=>{
    switch(data.action){
      case 'error':
        mainWindow.webContents.send('usb-error', {});

        break;
       //other cases [..]
    }
  });

usb.on('exit',(code,n)=>{
  mainWindow.webContents.send('usb-error', {});
  console.log('usb exited with exit code', code);
});

 usb.on('disconnect',(code,n)=>{
  mainWindow.webContents.send('usb-error', {});
  console.log('usb disconnected with exit code', code);
});

Those are the three codes that generate an error. Please note they could be launched in rapid succession.

tested against bortoworks
