Can all 20 devices be connected to one computer using only ONE of the USB out ports? (and similarly, can all 20 devices be connected to two separate computers by using both USB out ports?)

20 devices can be connected to one USB port of the computer, USB 3.0 is recommended, and the total USB bandwidth will be shared amongst all of the connected devices. Both USB inputs of the hub must be connected to the same computer, this hub is not to be connected to 2 computers.
