Created attachment 258331 [details] dmesg Hello, i'm using a Lenovo Carbon x1 (5th generation) with a HP Thunderbolt 3 dock (90W version). All ports are working, except USB Ports - for ~30 minutes. After ~30 minutes, also the USB ports get activated. While waiting for that, dmesg shows something like a "loop" through usb devices: [...] [ 389.023845] usb 3-1: new high-speed USB device number 55 using xhci_hcd [ 389.491841] usb 3-1: new high-speed USB device number 56 using xhci_hcd [ 389.959928] usb 3-1: new high-speed USB device number 57 using xhci_hcd [ 390.427925] usb 3-1: new high-speed USB device number 58 using xhci_hcd [ 390.895832] usb 3-1: new high-speed USB device number 59 using xhci_hcd [ 391.363817] usb 3-1: new high-speed USB device number 60 using xhci_hcd [ 391.831818] usb 3-1: new high-speed USB device number 61 using xhci_hcd [ 392.299759] usb 3-1: new high-speed USB device number 62 using xhci_hcd [ 392.771813] usb 3-1: new high-speed USB device number 63 using xhci_hcd [ 393.239765] usb 3-1: new high-speed USB device number 64 using xhci_hcd [...] Some lines which might be interesting: [ 13.908506] usb 3-2: 2:1: cannot get freq at ep 0x1 [ 14.058807] usb 3-2: 2:1: cannot get freq at ep 0x1 [ 14.210694] usb 3-2: 2:1: cannot get freq at ep 0x1 Best regards Matthias
Btw: HP Thunderbolt Dock 65W variant works like a charm, without his problem. Also interesting: USB devices (e.g. USB Keyboard) works, e.g. for boot menu selection, before booting the linux kernel.
