I get these in my log, I would like to filter them hopefullly without rebuilding the kernel:

Code:

Aug 21 09:43:59 ksp kernel: usb-storage: -- Result from auto-sense is 0

Aug 21 09:43:59 ksp kernel: usb-storage: Status code 0; transferred 31/31
Aug 21 09:43:59 ksp kernel: usb-storage: -- transfer complete


I use syslog-ng

Any hints?

If I recall correctly, you'll get that logspam if USB_DEBUG is set in your kernel options.

Go to your kernel source's menuconfig, and check if

Code:
Device Drivers --> USB support --> USB verbose debug messages

is set or not. If it is, unset it, recompile your kernel, and you should be golden.

But since you were looking to not recompile your kernel, it'd also probably be possible to filter that out using custom filter rules for syslog-ng. However, it might be difficult to do that, as the only common text between the messages is "usb-storage:", and I don't think you'd want to mask-out all USB storage-related information from your logs.

See the man page for syslog-ng.conf, and also check this page to get an idea of how to configure syslog-ng.
