More information about the hardware bug: https://xnux.eu/devices/feature/anx7688.html.
The author says: "This issue will be fixed in revision 1.2a". Also the author says: "It's therefore not possible to perform any kind of negotiation and communication over the USB-C CC pins. It's not fixable in SW. It's not possible to configure any USB-C peripherals correctly."
