I just bought a wireless keyboard (Rii mini 28). When I plugin the receiver into my windows laptop, it just works. I can type things in notepad and move the cursor.
But I bought it for my Android device: Ugoos UT4 OCTACORE ANDROID TV BOX. So I plugged the receiver into one of the USB ports. But I can not use it the way I used it for Windows. My android device ignores all my actions.
Any idea how I ensure my wireless keyboard works on my Android TV box?
