Hello--I'd like to eke a couple more years out of my mid-2011 Mini, and was looking into the Belkin F4U055WW dock as a way to add USB3 support. There are several on eBay at very good prices. Does anybody have experiences with these? I'm especially wondering if they work with hubs, and if USB devices stay connected when resuming from sleep, or if they have to be reconnected. There are alternatives, like the Kanex eSATA+USB3 Thunderbolt adapter and the Caldigit Thunderbolt station. Are these any better? Thanks!
