TUSB8020B Two port usb hub

Other Parts Discussed in Thread: TUSB8020B

I have some basic questions - 

I need really simple USB hub. I have two devices and I want to read from both through one USB.

I found TUSB8020B  but I have USB 2.0 connectors. The only thing I have to do is to connect all 4 pins to USB 2.0, other pins I leave opened? I do not need external clock, so I cal leave XI and Xo opened?

Is it possible that TUSB8020B  work only with 3.3V without 1.1V?

    Hi Marc,

    The TUSB8020B requires an external clock supply, so you will need to populate a crystal or an oscillator for XI / XO.  The TUSB8020B requires both 3.3V and 1.1V power rails to function.  You can leave the unused USB 3.0 ports open.
