Since yesterday I am getting message like the following at random intervals: ugen1.3: <Unknown> at usbus1 (disconnected) ugen1.3: <Unknown> at usbus1 (disconnected) ugen1.3: <Unknown> at usbus1 (disconnected) There are not matching messages about any connected device and usbconfig, obviously, knows nothing about ugen1.3: ugen6.1: <OHCI root HUB ATI> at usbus6, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE (0mA) ugen5.1: <EHCI root HUB ATI> at usbus5, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen4.1: <OHCI root HUB ATI> at usbus4, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE (0mA) ugen3.1: <OHCI root HUB ATI> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE (0mA) ugen2.1: <EHCI root HUB ATI> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.1: <OHCI root HUB ATI> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE (0mA) ugen0.1: <OHCI root HUB ATI> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE (0mA) ugen1.2: <USB Receiver Logitech> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (98mA) ugen2.2: <product 0x2514 vendor 0x0424> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (2mA) Seems like this is caused by flaky hardware? Or something else? Is there a way to stop the spam? Should we be reporting diconnects for unattached ports at all? Thanks! -- Andriy Gapon
