I originally used the 3DS capture card a few years ago, and I haven't used it recently. When I tried using it today, the capture software just gave me a black screen. Additionally, I believe that the 3DS capture card does not show up on my Device Manager (And yes, it was plugged in and the 3DS was turned on when I was trying this).
This is what I see: http://imgur.com/a/4vQCd
The 3DS capture was originally tried on another computer, and the computer was restarted, still no luck. Then I tried it on my own computer, tried redoing the drivers a few times, and I tried restarting my computer, and the same result each time. Tried using 2 different USB cables. Tried using USB 3.0 and USB 2.0 ports, neither worked.
From what I saw on some other threads from a few years ago, the USB port may be worn out? That sounds like something that would happen from a lot of use, and I haven't used it much, but maybe that's me just not understanding? Is there any way for me to check if it needs to be fixed/replaced? Are there any other things I can try to troubleshoot it? Is there some firmware update I need to do or something? I couldn't find anything else after searching for a while. Thanks for the help.
[Edit: And yes, I ordered it from here.]
