How to fix `Unexpected input report number 128` spam in logs?

  • 772

My logs are absolutely spammed with this message:

logitech-djreceiver 0003:046D:C537.0002: Unexpected input report number 128

I do a Logitech G602 mouse that I use. Is this spam fixable?

  1. The issue lies in the hid-logitech-dj driver which do not properly handle the G602 mouse and those generates this error message. Sadly the original author of the driver Nestor Lopez Casado [email protected] has decided to not take up the task to fix this issue. Some people have said that blacklisting the logitech drivers has removed the error, but not sure how well the mouse works after that.

  2. EDIT: Besides the bulky log (which log file contains those messages?), do mouse buttons work fine? If so, one can try to avoid such messages going into the log, like here.

    As per this, you might need a kernel upgrade. Please post the output of the following commands (I may extend the list depending on the output you post):

    $ uname -a

    This and this also show that the Logitech G602 is having issues with very recent kernels.

  3. FWIW, this continues to be an issue. Posted details into https://github.com/libratbag/libratbag/issues/832#issuecomment-1073410529 (related)
