I don't use the USB SuperDrive. I bought an LG slim external Blu-Ray burner that was on sale at Best Buy for $80. You get a lot more bang for your buck. I can even play Blu-Ray discs (thanks to the Leawo Blu-Ray Player freeware app; it can even play the Blu-Ray discs bypassing the HDCP thing on my 20" Apple Cinema Display!) and burn them (thanks to Roxio Toast Pro; a few months ago I burned my first Blu-Ray disc on my Mac Mini, of the HD videos I shot of my mother's 60th surprise birthday party.)
But for USB hubs, I use a Fideco hard drive docking station that includes two regular USB 3.0 ports and one for just charging devices. When the internal connections on my Seagate external USB 2.0 desktop drive (7200 RPM, even) failed, I was able to remove the drive from its case, plug it into the docking station, and it works very well, maybe even better due to the USB 3.0 connection! (Since it's a 7200 RPM drive, I use it for a lot of my video production work.)
