https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251503 Bug ID: 251503 Summary: Disconnecting/reconnecting USB-C dock makes other USB ports unusable Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: ali.abdallah@suse.com Created attachment 220135 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D220135&action= =3Dedit T495 usbconfig I have a T495 with the Lenovo USB-C docking station. When the dock is disconnected/reconnected (or when it looses power for an instant), other devices USB devices that are connected to the laptop are completely lost, such as the USB webcam, USB pen drive, etc... I can work around the problem to bring back those devices by: # devctl disable pci0:6:0:3 # devctl enable pci0:6:0:3 But obviously any previously mounted USB disk is lost I'm attaching 3 usbconfig files: usbconfig-inserted: original situation booting while dock inserted usbconfig-dock-removed: when the dock is removed usbconfig-dock-reinserted: when the dock is reinserted back, and other USB devices on xhci0 are lost. --=20 You are receiving this mail because: You are the assignee for the bug.=
