At first, It works well. but after reset my hub, It didn't works with my hub. I treid a lot, but there is no sign of join. I don't know why. Sellar communicate well, but they couldn't give me a solution.
I found how to reset it. Add and remove quicky to USB port several times. then suddenly LED is blinking. After reset it, I use it again, now.
