Linkit ONE Bricked

Hi,
I have a Linkit ONE which is probably bricked - means that cannont connect it via USB cable - COM port.
I have read user manual, tried all switch position without success - if I connect it to any computer (PC or Mac) it does not appear as a COM port. LEDs are green and red one is blinking in some switch position.
Is there any other way to factory reset (I tried to push reset button for a while) or connect it in a different way?
Thanks for your help.
