That sounds like an unsuitable hub.  Many USB 2 ones aren't very good.  I'd
suggest a USB 3.0 hub - you won't be connecting the USB 3 wires, but the
quality of chips inside is much better.

So no USB there.  However there is a USB OTG port, so with an adapter:

msung-Galaxy-S6-7-8-Edge/402308746179
(I searched for 'micro usb otg')

you should be able to connect another USB device.
