I have various FAT32-formatted USB sticks. They all work fine under eCS. I use DFSee to edit the LVM information. I set the drive letter to * and let the LVM assign the letter. Next time the stick is plugged in, eCS sees it. My Goodmans MP3 player also works fine, but a Philips GoGear still refuses stubbornly to play ball - maybe even this will work once the USB MSD support gets improved.
