Any suggestible USB 3.0 Hubs out there, that'll let me connect both a USB 3.0 External drive (for programs and video editing) and a wired mouse? I only ask because I tried some random small USB 3.0 hubs today, and to my surprise, both of them did not work when I had both an USB 3.0 external drive (housing a SSD) and a wired mouse connected to it. Is there a power issue that I'm not aware of for the single USB 3.0 port on the SP3? Is there not enough juice coming from the single USB 3.0 port to power both an external drive AND a wired mouse? FYI, the two hubs worked fine on my laptop and on my Desktop, but not on the SP3.
