So I just recently installed Ubuntu and today I discovered, that my kern.log and syslog files in /var/log/ are way to big (16.5GB and 13.0GB). I started to look into this, and discovered that the culprit was presumably the following line, which is spamed like a million time in both files.

kernel: [ 6292.136835] usb 3-1: cannot submit urb 0, error -2: endpoint not enabled 

I have absolutely no idea what causes this and I am also wondering how to stop that from happening?

Also, can I delete those two files, since they take up a lot of space and if yes how (can't right click and delete them).

EDIT: To clarify, the sound-card that caused the problem was the Kingston HyperX Amp and after not finding out on how to make it work, I returned it.

  • What is the USB device 3-1? You can check by lsusb. – Pilot6 Jun 14 at 14:10
  • Unplug all of your unnecessary USB devices and see if the problem with the logs stops. Reconnect one USB device at a time and see if the problem returns. – heynnema Jun 14 at 14:35
  • @Pilot6 Well I see a list now but how do I know which one is the device 3-1? Is 3 the bus and 1 the device number? – LetsFailNoob Jun 14 at 14:49
  • @heynnema I'll try doing it, but I already think, that my sound-card is causing the problem since it sometimes just stops working and then I have to reconnect it. – LetsFailNoob Jun 14 at 14:50
  • Is your sound card a USB device? – heynnema Jun 14 at 15:01

It was a USB sound card that caused the log entries. Removing the sound card stopped the log entries.

This is a problem with some USB device (Bus 3 Device 1).

It must be a hardware issue.
