I don't know, if it will be useful, but I made this procedure on USB3 port. On USB3 is not problem, but I can copy logs. Logs are attached.logs and traces from xhci could tell more details about what is going on, This line indicates a URB cancellation issues. To get xhci traces and logs please do: 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 < read EEPROM using the usb serial converter > Send output of dmesg Send content of /sys/kernel/debug/tracing/trace -Mathias
Is there any solution, how copy logs, when system is totally frozen? starosta
