Yeah and not only it makes your logs huge, but it also slows down your box using your CPU to flood while doing USB transfer.
On my old box, with CONFIG_USB_STORAGE_DEBUG set, syslog-ng eats 25% of my CPU when doing ntfs3g.
Totally something you want to turn off, unless you have serious issues with USB.
