Continuous messages in journal related to USB device.

[Tony Middleton]

I have a USB multi-card reader. When it is plugged in I get continuous messages in the journal

eg

Sep 14 16:55:16 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:55:16 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd

Sep 14 16:55:28 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:55:30 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:55:40 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:55:47 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:56:04 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:56:18 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:56:25 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd
Sep 14 16:56:35 rose kernel: usb 10-1.1: reset high-speed USB device number 6 using xhci_hcd

I have no idea whether this relates to a faulty device or a system problem.

Tony

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I've only noticed this recently but I don't look in the journal often so can't say how long the issue has been there.

I tried the 4.8 kernel. The messages were still there but lower frequency 2 or 3 per minute.
