Have had one for a year or so, was working perfectly. Just recently I noticed that it wasn't accepting IR commands (from the previously working remote). Checked it, and even though it's plugged in correctly, no red light is showing, and it appears it's simply dead. (I also tried moving the USB power plug to two different devices, just to make sure it wasn't some sort of firmware change to the Xbox 360 which I was previously using to power it.)
Any suggestions? Thanks!
