Logitech G502

I've been using my Logitech G502 Hero for about two months now, but it just died on me.
The only thing it’s doing is blinking that logo—that's it. No button clicks, no cursor movement, absolutely nothing.
Any idea how I can get this thing working again?

Have you tried plugging it into a different USB port on your PC—or better yet, testing it on another computer entirely? If you’ve already done that and it’s still acting up, then it’s likely dead. If you've still got the warranty, I'd say just take it back to the store for a replacement.
