--- Comment #6 from Mathias Nyman (mathias.nyman@linux.intel.com) ---
Could you share both dynamic debug and trace of this case?
If possible remove as all extra usb devices before triggering this, as logs
gets clogged and hard to read.

mount -t debugfs none /sys/kernel/debug
echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control
echo 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control
echo 81920 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/xhci-hcd/enable
echo 1 > /sys/kernel/debug/tracing/tracing_on
< Reproduce issue, connect problematic device >
Send output of dmesg
Send content of /sys/kernel/debug/tracing/trace

I'll try to find reproduce this on our local Lunar Lake one I get my hands on
some failing devices, my current USB3 ethernet adapter unfortunately has a ASIX
chip, not Realtek.
