cp --preserve=all is documented as suppressing operation not supported messages, and cp -a (archive) is documented as suppressing messages about inability to preserve information which can not be stored on the target filesystem. Alternatively, instead of using the default USB DOS/VFAT format, you could format the USB drives as NTFS, which would allow cp to preserve the ownership and ACLs on the files.
