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. |
