To get xhci traces and logs please do:
mount -t debugfs none /sys/kernel/debug
I get message:
mount: /sys/kernel/debug: none already mounted or mount point busy.
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
< read EEPROM using the usb serial converter >
Send output of dmesg
Send content of /sys/kernel/debug/tracing/trace
I made all as you wrote, but problem is, that the system completely
freezes and I must power it off.
After power up there is not any logs (header only) in
/sys/kernel/debug/tracing/trace.
dmesg created before eeprom reading: https://paste.ee/p/xb16H
