they are on different host controller ports (on your PC/motherboard).
They are indeed, one hub on the front ports one on the back ports. One of the back ports has become intermittent so though I would save the rest of the ports with the hubs.
Amazon must have mixed stock. The first hub I got was V5 hardware (no port leds) but the second was a V4 with port leds.
One thing I have noticed doing speedtests on disks Linux is a bit slower than Win 11. eg. Crucial X9 and Crucial X6 portable SSDs are slower than when tested with CrystalDiskMark in Windows. Guess I know which OS to do lots of file transfers!
