Fire TV 3 supports USB Peripherals via OTG Cable — Including USB Drives, Keyboards, Mice, FLIRC, Ethernet, Hubs, etc…

Much like the Fire TV Stick 2 before it, the new Fire TV 3 supports external peripherals through a USB OTG cable. This means that, despite not having any external ports, you can still connect things like USB drives, keyboards, mice, game controllers, ethernet adapters, and more.
