>If this just requires USB and HDMI, it should theoretically work identically a for Mac Mini or even something like a Fire TV, yes?

I believe so, but with the caveat that I haven't tested it. Does Fire TV take USB keyboard input?

I have successfully captured video from a Roku Premiere[0], even though it's HDCP protected. The LKV373A couldn't capture anything out of it, but the $11 dongle did just fine. But that was just video capture. I didn't have a way of sending input to the Roku.

>Is there an upper limit on resolution and frame rate for the dongle?

Yes, the limit is 1280x720px @ 30FPS.

I have a Fire TV brick (not stick) and it has a USB A port that I've successfully used with a mouse at least. I don't have a keyboard handy to test.
