My PC only has USB-A ports. I want a hub which I can connect (so it needs USB-A connection) and which provides both USB-A and USB-C ports. I do not need any of the fancy optional features USB-C can provide like Thunderbolt, DisplayPort or high power output, just plain USB 3 will do.
The only devices I could find so far are of the Docking Station category with a very steep price tag. All the normal hubs I found with USB-C ports have a USB-C uplink connection as well.
The lack of such a device made me wonder, if there might be a technical (or legal) reason that such a device cannot exist.
