I am actually writing OS Descriptor support for libusbgx (fork of
libusbg) when I stumbled upon this. The helper function there do not
care about the new line, but I just thought we should fix it for the
sake of coherency to the other properties. I am also fine dropping this
patch.

Do you happen to know where the source of that part is? So we could
check if they make use of any OS Descriptor support yet...
