USB error

Post by wp.rauchholz » 2018/08/19 07:30:12

when I turn on my centos I am gettign the following error (copied from /var/log/messages):

Aug 19 09:09:11 home kernel: usb-storage 1-8:1.0: USB Mass Storage device detected

This is a new error. I did not change anything on the config
I run CENTOs 7 on a headless server. OS is updated to latest version.

Any hint how to fix this is greatly appreciated.


Thank you, Wolfgang

What is this USB device? Try unplugging all USB devices you have, and plug them in again one by one, and see if you get any error messages when you plug that device in. lsusb -v may also show you something.

Thank you for picking up. Not solved yet. I unplugged all 3 external USB devices and re-started. The error persists.
I ran lsusb -v and also lsusb -t, but neither of that resulted a hint.
Centos attempts to assign an address is unsuccessful and stops at some point. The 'unable to enumerate USB device' statement is the last of a long list of attempts to assign such address.

Aug 21 12:00:35 home kernel: usb usb1-port9: unable to enumerate USB device

The external hard disks work fine and as a matter of fact I can't detect any running problem with my server. But I am concerned that these messages just are the symptom of a bigger issue I'd like to identify.
Thanks again for your help.

Try the problem device (did you tell us what it is?) via a powered USB hub and see if that helps. By a powered USB hub I mean a USB hub that has its own power supply and is not powered by the host system's usb bus.
