Okay, so I'm making an effort to significantly cut down on the number of mains adapters my computer setup currently has, which means trying to replace some of the many external drive docks and other detritus I have. Anyway, one of the things I have is a 5-port gigabit ethernet switch, though I probably really only need three ports (one for my computer, one for a games console, and one for the network connection). What I'm wondering is if anyone knows of any switches that don't require a power adapter (are there any powered by USB for example)? Or just alternatives I could consider. For example, has anyone tried using a USB3 to ethernet adapter (or a thunderbolt to ethernet adapter) to share a network connection with a games-console? I remember trying it ages ago with my XBox 360 but not having much luck, but then that could have been because I was trying (in vain) to make do with a wireless network at the time. It just seems like something I probably don't really need, seeing as how I don't need all four of the extra ports it gives me. Also bear in mind that I'm planning to switch my 2008 Mac Pro for a Mac Mini, so I'll be losing the second built-in ethernet port.
