So you use WSUSOU directly on the USB drive? The flash USB might be formatted with the FAT32 filesystem. FAT32 uses very imprecise timestamps (two-seconds-granularity). Thus the 'file is newer/not newer' check is bound to fail.
You might get better results with the flash USB formatted to NTFS or exFAT.
