I've just bought a DSi USB charger so I can look through the files on my DSi menu on the computer and place games onto the DSi menu. Everything is working, but the computer has no reaction. What do I do?

You'll probably have to go to your control panel and find devices and printers and put it in so the PC can recognize the device. There are a few ways in the control panel to do this, depending on what OS you have. Your PC just isn't recognizing it is all.
