This transaction error is probably due to device disconnect.=20 Transfer events for TRB ..a1c0 twice, with a transaction error in between: -0 [000] d.h2. 33819.709897: xhci_handle_event: EVENT: TRB 00000032959a1c0 status 'Success' len 0 slot 6 ep 2 type 'Transfer Event' fl= ags e:c -0 [000] d.h2. 33819.709904: xhci_handle_event: EVENT: TRB 000000041547d010 status 'USB Transaction Error' len 4 slot 6 ep 15 type 'Transfer Event' flags e:c systemd-journal-395 [000] d.H1. 33819.711886: xhci_handle_event: EVENT: TRB 000000032959a1c0 status 'Success' len 0 slot 6 ep 2 type 'Transfer Even= t' flags e:c Transfer events for TRB ..a1d0 twice (the next TRB) systemd-journal-395 [000] d.H1. 33819.712001: xhci_handle_event: EVENT: TRB 000000032959a1d0 status 'Success' len 0 slot 6 ep 2 type 'Transfer Even= t' flags e:c systemd-journal-395 [000] d.H1. 33819.712059: xhci_handle_event: EVENT: TRB 000000032959a1d0 status 'Success' len 0 slot 6 ep 2 type 'Transfer Even= t' flags e:c Transfer events for TRB ..a1e0 twice systemd-journal-395 [000] d.H1. 33819.712139: xhci_handle_event: EVENT: TRB 000000032959a1e0 status 'Success' len 0 slot 6 ep 2 type 'Transfer Even= t' flags e:c systemd-journal-395 [000] d.h1. 33819.712871: xhci_handle_event: EVENT: TRB 000000032959a1e0 status 'Success' len 0 slot 6 ep 2 type 'Transfer Even= t' flags e:c etc.. Driver can cope with these extra events, but if this is common we should probably handle it silently and not concern users with that ERROR message. --=20 You may reply to this email to add a comment.
