So this may sound like a "why would you want to do that?" question; but bear with me. To keep things "clean" in our family room, all of my A/V gear is actually in the room behind where our TV is mounted. Every now and then the remote gets a bit slow to act or just downright unresponsive. I fear it is because the NSZ-GS7 is about 15 ft. away from where we typically sit, and behind a wall. I'd rather not have to bring the unit into the room; as, aside from there being a black box that I would rather have hidden, it adds some challenges to using its IR blaster. But what I thought I might be able to do is use a USB extension cable and a USB Bluetooth dongle to bring just the BT receiver portion on the "good" side of the wall. Has anyone tried something like this? Any chance of it working? Or would it simply compete/confuse the built-in BT receiver?
