Those look like some knockoff stuff and should technically work as they are. The official boards have a Fuse, Common Mode Choke, TVS array and decoupling Cap on them, plus the USB, LED and connector. Looks like they traced straight thru where the Fuse would go, so no point in installing that. Same goes for the Common Mode Choke as it looks to be traced thru as well or the D+/D- lines solder jumperd closed. The TVS and decoupling cap aren't required for it to work at all.
