My 2010 MBP only has USB 2.0 and no express card slot to fit an adaptor (works great on my 2006 MBP by the way) However have come up with idea. I have a thunderbolt to HDMI adaptor with is obviously capable of high speed transfer rates and 2 way traffic. If I buy a USB 3.0 to HDMI connector which does the same and connect the 2 together, in theory it should give me a usb 3.0 connection via the Thunderbolt port. Total cost £20 verses £80 for a thunderbolt hub. Anyone know whether this will work?
