i'm wondering if that usb hub usable and stable, for example, not outputting ridiculous voltages to your controller equipment (Pi or whatever)? or is it shitty as well and need to be replaced?
i guess usb hub is one of the most important components to provide good stability and smooth operation these devices.
It's a standard 10 port usb hub, I'm using 5 of them over the last month and there wasn't any issue ...
In my opinion the usb hub is more then fine ...
