Today I got the Elgato Thunderbolt 2 Dock that I bought for my Macbook Pro 13 inch mid 2009, but I can't figure out how to access e.g. a USB stick via the dock.
I don't think the MacBook 2009 has a Thunderbolt port, only a mini Display Port. They look identical, but they are 2 different ports. That's why it can't work either
