Compatibility with USB3

I have the new Mac Pro (6.1) with both USB3 and Thunderbolt connections. Due to the fact that any additional storage have to be external, and I have already several USB3 drives (OWC and QVoyager), I have added an Anker USB3 hub (9 ports).
For SD backups of the system disk I'm now using a Crucial M500 480 GB SSD in an OWC Mercury Elite pro enclosure. No problems, effective copy speed varies from 80 to 300 MB/s. The disk may be plugged into the hub, or directly to the Mac . No marked difference.
Booting from the Crucial disk is another matter. When connected to the hub , it won't boot, although it is displayed as "startup disk" in System Preferences. Furthermore, it is not displayed as a bootable option by an "Alt-Boot".
But if connected directly to an USB3 port on the Mac it boots OK.
So I don't worry but I'd like to know if some of you have experience of booting from USB3 on a hub (and which one ?) .
