A couple of notes:You think video output does not work via such an USB-A to -C Gen 2 cable or adapter?
(like this one
)
I have a brand new Asus ZenBook 14 UX434FAC with Comet Lake CPU that offers both USB-A and USB-C with 3.1 Gen 2, but it is hard to find out what they actually support compared to Thunderbolt, and also a pain to find compatible hubs and devices.
- I have bought several adapters like the one you listed here (off Aliexpress, but I would assume they are all made by the same OEM given the identical designs) and none of them actually worked above USB 2.0 speeds on any of my devices (Ryzen desktop, TR desktop, Intel laptop). I finally found some working ones, but they were an entirely different design:

- Your laptop has a poor spec sheet, but I would assume it supports DP alt mode - most do these days. It is of course possible that they skipped it, but that would be surprising on a relatively premium device like that. I would assume that it doesn't support PD charging given the lack of mention of it, but the only way to know is to test it (or find a review). As for compatibility with hubs, these two points are the only ones in question - whether charging and display output through the hub will work. Beyond that a USB hub is a USB hub, and all features on it should work when connected to any USB host (just at variable speed dependent on the host). Anything beyond USB ports, charging and display outputs is handled by USB-connected controllers in the hub, so compatibility should be entirely universal whether it is an SD card reader, ethernet port, or anything else. The U in USB stands for Universal, after all, and all USB devices should be backwards compatible. The only thing that might throw a wrench in the works of this is whether the hub needs more power than a type-A port can deliver, though that seems unlikely unless you're plugging it full of power hungry devices.
