    OS X USB 2.0 detection


    Is there a way to determine if OS X is seeing a USB device as USB 1.x vs 2.0? I have an external 120GB hard drive and DVD/RW that seem to pseudo-randomly go from 1.x to 2.x when I plug them in.

    Thanks, I was able to find that it's seeing my USB hubs as 1.0 hubs (12Mb/s) instead of 2.0 (400 Mb/s). It seems to only see my drives as 2.0 when I don't use the hubs -/
