USB 3.0 can do 5 Gbps. USB 2.0 can do 480 Mbit/s, or 53 M bytes/s. Seriously Onyx does significantly more than 53 M Bytes/s?

Also you can get cables with tethered adaptors as well as separate adaptors. Really I don't care if an ereader has micro, mini or C type connectors. If the socket or plug isn't obvious in orientation I put a line of white or black on.

Also I have a four USB 3.x speed HDDs. One has USB-B connector with extra part for "USB-B USB 3.0", one has a USB-A (9 pin USB 3.0) socket and uses a back to back USB 3.0 USB A cable, one uses a mini-USB USB3.0 (extra part) and one has a captive cable with USB 3.0 USB-C plug.

I've ereaders that use micro, mini and USB-C. None are USB 3.0. The higher speed charging on Kobos with USB-C use only 4 wires, so a suitable Qualcomm compatible USB-A port (4 wire, not USB 3.0 9 wire) charger works.

Ditto on phones and tablets.

The audio, video, network, power in/out modes, charging modes, USB 2.x / USB 3.x options are a minefield on USB-C. You have to test each gadget, adaptor and USB-C cable and PC port to establish what works. The makers and sellers mostly don't say.

Very many things with USB-C connectors have the same internal circuit as if they had micro USB.

I've now stupid power tools that need specific USB-C chargers. They don't charge on any of my regular chargers for USB-C. I think only my Chromebook charger works.
I have a multi-plug USB cable that has a slow speed USB-C cable. I use it for when something with USB-C cannot handle high-speed charging.
