Will try again in about 2 - 3 hours with only 1 drive connected to the hub so there won't be any more confussion. All drives work just fine when connected directly to the usb ports in the asrock. They also work just fine ( it seems ) when connected through the usb hub to my laptop. And as I said, both have the same usb3 hub chip that's why I think it's weird. Anyhow, will get you more debug in a couple of hours.
