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.
i own couple of such industrial psus. these aren't really that shitty at all. voltages are as pretty stable and the quality is reliable enough. of course, these aren't meant for open area installation like your average pc toys..
