There is currently no way to connect the Nintendo DS to any USB capable device. THat is a real shame because there are many USB storage devices out there and a USB slot could greatly increase the Nintendo DS’s capablities in dealing with a variety of mediums. However with the AceKard 2 you can indirectly connect the Nintendo DS Lite to a device. This is because the Acekard acts as an intermediate for when you want to connect the DS to some sort of storage device like a MicroSD card and upload your very own custom content onto the device.
