If I get USB MSD to work, you only need to make the PC think there is a file system by giving the PC fake sector data. You can either plug your project directly to your PC via USB, or make a sd card reader to convert the simple file system to a fake file system the PC can understand. >From what I understand, you want something small. Any project with USB is not small. But as discussed on Jallist, USB MSD can be held in program memory and not take any RAM space until USB is needed. The USB program would be called with a goto, and there would be another goto to get back to the main program. You could also pre-write a bunch of files, ore even just one file, to a sd card with your favorite file system and know where the files are before you write your PIC program. As Seb said, "You could also just write data on sd-card, without any file system at all" but in this case, there is a file system but you are ignoring it.
