Doing what exactly? In general this is informational output when a sync happens. This can happen for various reasons, for example actually using the sync command, using an app that uses fsync() (like svn) or when unmounting volumes. The usb_disk related output just indicates that the device in question doesn't support syncing. It will try a few times and then won't retry anymore. Unless this actually does flood, i.e. there's something going on consuming considerable CPU time, I'd like to close this as invalid.

I get these line also when the PC is idle.

It keeps outputting these messages. Get a few per minute, idle or not. It somewhat pollutes the syslog, and I personally don't see the need for them. Let me know if you need more information.
