OK, what useful and passive #USB gadgets do you know of?

For (boring) reasons, I need a solid-unit socket doubler like the one pictured. All the ones I can find also have integrated USB ports.

This is going to live behind a cupboard with pretty restricted access.

What can I plug in to make use of two USB sockets?

Suggestions gratefully received.
