I bought this device because of its switching function but the first thing I did was connect it to my computer and update the firmware to the latest version (v1.33) which I think was 1 version higher than the adapters . from the box. I was able to sync the adapter with the controllers very easily. The synced controller worked fine on the computer. Then I connected the adapter to the switch. The adapter synced with the controller just fine BUT the switch didn't recognize the controller (yes, with wired controller pairing enabled). I've tried syncing to different controllers, re-syncing controllers over and over again to no avail. When I flashed the adapter to a previous firmware version (I think it was v1.30 or v1.31) everything worked as expected. That being said, if I hadn't flashed the device to the latest firmware, it might have worked right away. The fact that the latest firmware worked on the computer without any problems led me to believe that the adapter just doesn't work on the switch, which made me pass out for 10-15 minutes. Again, it goes without saying that once the adapter was flashed to a previous firmware version, THEN it worked as expected. Also, I will inform the manufacturer about this problem. If it wasn't for this problem I would probably give 5 stars.
