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
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.
