Yes, a USB extension cable in internal format
The male and female connectors on the extension cable are compatible. I had received a so-called USB extension cable from a supplier other than LDLC where the 2 plugs were not the same format, which I call an adapter and not an extension cable, and I returned the product.
No problem here, everything is as described, and I was able to reach my motherboard socket to plug into a large tower.
