Is the USB formatted to FAT32?
Usually "No applicable firmware was found" is the PS3 cannot find the PS3UPDAT.PUP
Either
1. folder structure is incorrect PS3\UPDATE\PS3UPDAT.PUP
2. the PS3UPDAT.PUP is not named properly or correctly
3. USB is not recognized because the file system needs to be on FAT32
