New 3DS XL not detected by Computer.

It sounds like your computer doesn't recognize that it's plugged in at all. That would be a hardware problem.
Could be a damaged connector. Or the board is fried. Or you're using the wrong kind of cable (only for charging).

When I sent it to you . You told me nothing was wrong with the card. I've tried every cable known to man. Purchased a bunch of different types. Nothing...
BUT.....

Just now I decided to plug it in again after a week of not trying and Magically it worked. WHY? I DON'T KNOW. It doesn't make any sense. I fear it happening again without any explanation. But for now I'll just be happy its working again.

When I used it with my laptop a couple of months back, it worked fine. Didn't use it for a couple of months, and tried using it on my desktop, that's when I noticed it didn't work. I tried it on my laptop again, and it didn't work there anymore either. The cables I've used are for both charging and data transfer. I use them to capture video from my Nintendo Switch, and Playdate. I also tried two drivers for the 3ds capture card, the latest one, and the previous one it worked on. Neither one worked.

Same issue, works fine on my Windows 10 laptop, not detected at all on my Windows 11 desktop (not sure if that has to do with the operating system or what)

EDIT: Issue has been resolved, only USB 3.0 on the rear IO of my desktop recognizes the capture card. Either than that hiccup, the capture card works amazing on the desktop. No complaints right now.
