Hi,

Does u-boot see the XHCI controller?
I had to backport u-boot changes to sysutils/u-boot-rock64
(sysutils/u-boot-master) 2023.07.02 to get it working in
u-boot and 14.0-ALPHA1 for Rock64 and Orange Pi R1 Plus.

I took the following (I don't know if all are needed):
https://source.denx.de/u-boot/u-boot/-/commit/caaeac88466f4152bd126e2342765a4b740955ae
https://source.denx.de/u-boot/u-boot/-/commit/b71f74eab42782199757e146483126aee5e3c271
https://source.denx.de/u-boot/u-boot/-/commit/559911ff2ed09812fc0a87513183a44d9ee100cf

https://source.denx.de/u-boot/u-boot/-/commit/b6fd3c63f4c5ba8cad518fa34e6a3289a6976f2e

For Orange Pi R1 Plus I also needed the patch adding it:
https://source.denx.de/u-boot/u-boot/-/commit/69e16c7b1cdd03907b86bb31abee24f5d4836400

Unfortunately, there is some issue with the XHCI controller, at list with
Realtek RTL8153 USB nic (built in on R1 Plus and tested external card
plugged into Rock64) so it might have issues for other USB devices too.
The nic doesn't work until the USB bus is reset and can get stuck again.
It didn't work on 13.x either.
