I tried with a USB3 hub connected to a usb3 port, a sata
adapter connected to the USB3 hub, and a SATA disk connected to the
SATA adapter, and I could read the disk.
The difference is that in my tree both the USB2 and the USB 3 hub
hang from the XHCI controller, not one from EHCI and one from XHCI.
This with my v5 patches on top of 4eb7c5030d3f3c70 (2023-02-19) and some
minor config changes that don't seem to matter.

I don't know how to help, maybe just try to increase log verbosity or
something...
Sorry
