Why only a single USB-C port? Almost everything I buy these days has only USB-C ports/cables/charging. It's gotten to the point now that I am increasingly frustrated with the fact that there are no good USB-C capable hubs that take a USB-C USB 4 and turn it into an 8 port USB-C hub. With a mix of 10 Gbps/5 Gbps/480 Mbps speeds. I can get plenty of USB-C to USB-A hubs, but that is not what I want.
> 8 port USB-C hub
And I believe a major reason for the lack of these, is that, if a dock/hub/etc. that consumes a USB4/Thunderbolt host port, wants to be able to expose a full-speed USB4/Thunderbolt downstream port of its own, then that port isn't going to work for peripherals that are picky about speeds/lanes if you have any other USB devices plugged into the hub. So vendors choose "the ability to plug a single Thunderbolt device in, plus other things" over "the ability to plug a bunch of USB4/3.2 devices in."
