Also traces and logs with more usb details enabled could be useful. These can be taken with any recent kernel. 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 < connect the logitec device > Send output of dmesg Send content of /sys/kernel/debug/tracing/trace -- You are receiving this mail because: You are watching the assignee of the bug.
