You can currently not connect a DSi to a computer VIA cable, but you can use an SD card. With this you can manage photos and audio.
You would plug in a USB cable to the computer, and the other end of the cord connected to a Nintendo DSi.
The DSiware games are downloaded to your DSi and appear on its menu. You do not need to be connected to the internet to play those games.
Once you have connected your DSi to the Internet, go on the icon on the DSi Menu that has the two shopping bags - this is the Shop Icon. You can then buy things with your DSi points.
you need a modern that conect to the internet. then go on ur dsi seeting>press internet (on the third page)>press connection setting> none> then tap the top option. make sure you modern has connected to a internet and it is on. u also have to connect it to the computer but you do not have to put the computer on while going on the internet on the dsi.
You can use it to charge your DSi from a computer. It is a cable that has a usb (pc) connector on one end and a DSi connector on the other end. Your computer needs to be on for this to work.
You probably are not connected to the internet. you need to be connected to the internet to access the shop. If you don't know how to connect, go into setting and click internet.
