itunes seems to be able to work with the iphone (sync, backup). But the syslog is flooded with theses warnings.

PascalC, thank you for reporting this and helping make Ubuntu better.

As per https://downloadcenter.intel.com/search?keyword=NUC5i5RY an update to your computer's buggy and outdated BIOS is available (0354). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

Same error here. I've updated BIOS of my barebone ASUS M42 and it keeps flooding my syslog:

xhci_hcd 0000:00:14.0: WARN Event TRB for slot 1 ep 2 with no TDs queued?

I think it is related to usb/smartcard reader

Ubuntu 15.10 server x64
Linux ubuntu 4.2.0-30-generic

How can I silence this error msg from syslog?

Thank you!

ubunyo, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.
