Earlier this week, Roku announced its refreshed line of media streaming sticks and boxes. The standouts of the pack are the new Streaming Stick+ and Ultra box, both of which support 4K HDR video and have a new voice-powered remote with buttons for controlling a TV’s power and volume. The new hardware should be shipping to customers next week, and we just got our demo devices in The Verge offices for review.

Naturally, as I do with most review devices that hit my desk, I immediately ripped open the Streaming Stick+ to see the hardware and what comes in the box. And what was staring me in the face is something I haven’t seen in years: a Mini USB port.
