USB 3.0 drive and USB 2.0 hub does not work puzzle

So I am trying to use a USB 3.0 drive with a USB 2.0 powered hub. I don't care about the speed I just need the connectivity.

If I plug the Seagate USB 3.0 drive directly into the computer using a USB 2.0 cable it works.

If I put a powered USB 2.0 hub (tried two I have around) inline the LED comes on in the drive case but I don't see the drive show up on the computer.

Any ideas? Are there certain powered USB 2.0 hubs that don't like newer drives?
 
Does it show up in disk management but just as unallocated? If it's there maybe try assigning a drive letter to it.
 
Thanks of the idea, it is a Linux system but I tried watch dmesg for a while and tried different ports.

For some reason it seems to reset a couple of times but then it started working, yay!

This is what I get when I plug it in directly:

Maybe this is a USB high-speed vs full-speed issue.
