I'm sorry but I haven't been able to reproduce your issue.

Unfortunately I don't think I have any usb-ethernet dongle here to test...

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
