Reader usually works right out of box but sometimes you will need more information to get it working. Here is some Important and helpful tips: Does not work with iPhones, iTouch, stick pro duo, Flash drives, HC SD cards, PNY, Sony Memory Cards Only designed to recognize JPEG files. DOES NOT WORK FOR VIDEOS Works with SD Cards (under 24gb), Micro SD Cards and USB Plugs Make sure the USB drive is formatted as FAT32 - Create a folder in the root of the USB drive called DCIM - Make sure the file names of the pics are exactly 8 alphanumeric characters long plus a supported extension - File names must be letters and numbers ONLY - Make sure all pics end in the .jpg extension (NOT .jpeg) - (if attempting to transfer videos Make sure the videos are of a supported type: .mp4, .m4v and maybe .mov. This may work but generally videos are NOT compatible) - Folders inside the DCIM folder can be used if they are 8 alphanumeric characters long - The USB drive must use 20mA or LESS power or it will not work. - You can get USB drives that use more than 20mA of power to work by using a wall powered USB hub The filenames MUST start with at least DSC and be only eight characters total without any spaces. Using all caps or all lower case for "dsc" or ".jpg" did not matter. The other 5 characters after the DSC did not matter, but you could not use a space. Example: DSCNNuge.JPG; dscnNuge.jpg; dscnnuge.JPG; DSC0nuge.jpg would all work.
