Can you provide details on your non-working hubs?
One of the USB 2.0 hubs was an unbranded generic oriental import.
The PCB inside it states a brand "xinbolo" and the USB chip is HS8836
This hub works perfectly on Windows, but if I attempt to use it on a Pi, nothing will work (testing with a mouse / keyboard)
Another USB 2.0 hub, integrated with a multi card reader, with the hub chip, LD35645812037C also works with Windows, but not my Pi.
A third USB 2.0 hub, L83J697B6064C, also behaves in the same manner. It is manufactured by the same manufacturer as the second hub.
A fourth USB 3.0 hub does work. I have no further info about this hub as it is unbranded and I am reluctant to break it open.
I also had a different USB 3.0 hub that worked - at least until the detachable USB 3 cable ripped the traces from the board one day due to poor quality design.
I still have it somewhere, hoping to one day be able to repair it, but for now all I can offer about that is the serial number off the case, 71624912062909
There is no brand, it is merely labelled "USB 3.0 4-Port Hub"
All were bought from reputable retailers except the first usb hub I mentioned which was bought from an oriental import bargain store.
