It's good that you're able to use the newer kernel version, despite it not being Mainline. We'll see how far we can get with v6.9.10. I have to make some assumptions that the dwc3 and xhci drivers are not modified. Can you provide feedbacks on these to give us some clues: * Did you enable any quirk in your controller (from the old kernel)? * For the devices that do work, what speed can they operate? Can they work in both SuperSpeed and Highspeed? * Have you tried disabling power savings? (Check if you have "usb3-lpm-capable" or "usb2-lpm-disable") * Does reloading the xhci driver recover the issue? * Can you capture the dmesg and xhci tracepoints of the issue for the newer kernel?
