Fast data logger for multiple analog pins

fat16lib-

Allow me to ask another way. Say you store your data to an SD card and you want to enable the user to get the data without removing the SD card from your device. If you had a USB host breakout, how could you move the files from the SD card to the USB host such that a user could attach a flash drive/memory stick or their computer to the USB port and retrieve the files?

Thanks!
