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

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.

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
Comment 3 Matthias Lohr 2017-09-13 06:34:03 UTC
Done. What should i do with this ticket?
Comment 4 Matthias Lohr 2017-10-20 06:32:29 UTC
Patch accepted, should be in the next kernel release.
