https://bugzilla.kernel.org/show_bug.cgi?id=218118 --- Comment #4 from Andrew (quark@xxxxxxxxxxx) --- Unfortinally 'usbcore.dyndbg=+p xhci_hcd.dyndbg=+p' did not gave more information about usb3 issue. Maybe I need to add some extra option to kernel config and recompile? I tried to plug in mouse to usb3 port instead of flash-drive, and there was no light under mouse. And 'usb usb3-port1: connect-debounce failed' appeared at dmesg. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
