I don't have a quote from the manuals, but I believe any flash drive that conforms to the USB Mass Storage Device spec will work (which is almost all of them). One thing to check is to make sure that the drive is formatted with the FAT filesystem. Microsoft's NTFS or Apple's HFS may not work with the Linux OS that the DS uses.

Also, make sure you're following the directions and placing the file named DSUD_PKG.BIN into the root directory of the drive (i.e. not in a folder).

If these suggestions don't work, maybe try listing what you've tried so far so we can give better suggestions.
