My early 2011 Macbook Pro has two USB 2 ports that are very flaky. i believe the only other port i can utilize is the minidisplayport/thunderbolt 1 opening. i am trying to locate the right adapter or hub that will allow me to at least plug in USB 2 cables, preferably multiples at once. a hub might be preferred, one that includes thunderbolt, ethernet, firewire, etc. any advice is appreciated!
