Hi everyone,
I noticed a few days ago that I am getting frequent errors from xhci-hcd in the system log of my Raspberry Pi 4:
The first of these messages corresponds with the day I installed a USB audio interface and all the following errors of this type seem to have occurred when I was using this interface to play music.
All the while, the playback and the rest of the system seem to be working fine to me.
Nevertheless, I would like to get this confusing error messages out of my logs.
I tried to run the USB sound card on different USB ports (both USB2 and USB3) but always get the exact same error.
When I install the sound card on an different Raspberry Pi 3 running the same OS and using the same command to play audio on it there are no errors.
I also found this recent post of a user running Ubuntu on his Raspberry Pi and experiencing this exact same issue. So the problem does not seem to be exclusive to Raspberry Pi OS or the Nextcloud image.
Unfortunately I was not yet able to register an account there and to contribute to that post because I keep being blocked by their security system. I am currently trying to sort out this issue with their support team.
However there have not been any replies to this post for 20 days so I decided to find help here.
Does anyone have an idea on how I could nail down what causes this error message? Or better even fix it?
Should I be worried about this at all?
Background:
I am running the Pi for quite some time as a cloud server on a NextcloudPi image. The OS is currently Raspberry Pi OS Bookworm but the same errors were logged back when I was still running Bullseye.
A few months ago I installed Raspotify on the same system to stream music to my stereo through the Pi.
At that time I also installed the USB audio interface to achieve better audio quality than the integrated PWM output provides.
Thank you for your help!
