hi so my usb 3.0 hub that has always ran at usb 3.0 speeds on my mac pro 2013 and imac 2013 i was using it for a bit on my 2010 imac that is usb 2.0 speeds and now that i brought it back to my 2013 mac pro the dang thing is stuck at usb 2.0 speeds. this has happened to me with other usb 3.0 devices but for some reason it will not switch back to usb 3.0? ive tried thing like pram and switching and switch ports and everything but this dang thing is stuck at usb 2.0 speeds.
