The 'dmesg' is very clear, but looks still no bad things found, we
can see USB1/USB4 are USB2.0 bus, and built-in devices are
recognized in USB1 bus, but I am not sure the external USB 2.0 ports
belong to which bus(1 or 4).
Could you do the below tests so that we can see if USB4 bus can be
wakeup? If not, the problem should be that something is wrong with
port routing setting.
- plug one device into USB 2.0 port
- run the below scripts and post out the 'dmesg' info:
#!/bin/sh
find /sys/bus/usb/devices/*/power/control | while read LINE; do
echo on > ${LINE}; done
Thanks,
