First of all it's not a USB 3.2 hub. I tested the card reader unfortunately it is slow (first screenshot), I could only get 1/2 of the reading speed, system profiler showed that the reader is USB3.0 (up to 5 Gb/s). After that I inserted SanDisk microSD reader to the hub and tested again (second screenshot), reading speed was as expected and system profile confirmed that the hub is USB 3.1 (up to 10 Gb/s). Another thing I didn't like is that it gets very warm. Overall the hub is not perfect but ok.
