Apparently this annoying, stupid variable was leaking before the ComPtr was added, which ironically was necessary to ensure devices worked. After that ComPtr commit some devices stopped capturing properly. Basically, it implies that this pointer needs to stick around while the device is in use. (Jim note: This was one of the most painful things I've ever had to debug)
