I'm using a SanDisk Cruzer 8GB USB and it is not being recognized by my F90BT. Any MORE ideas? I've used SEARCH and tried the following so far: Removed U3, deleted and created new partition/reformatted in FAT and FAT32 (won't let me in NTFS, even if force formatted), tried different folder names, file types, etc. Why isn't the F90BT recognizing its there? The light on the USB comes on so it's getting power... ? Thanks in advance.
