If you want to get the modules of all devices loaded automatically, enable
`udevsynthetize` in `/etc/udev/udev.conf`. This is experimental and not fully
tested though.
== What about hotplug? Will my pendrive work? ==
- Hotplug included in current udev replaces the old hotplug completely.
Paralell work of both is rather not advisable, so after udev's installation the
old hotplug is uninstalled.

== I'd like to connect my digital camera/scanner/other USB device to my
computer. Do I have to mount /proc/bus/usb with proper permissions? ==
- Absolutely not. Install `udev-digicam` package, add yourself to the digicam
group, and udev's agent will do the rest, no matter if that's a scanner or
other USB input device you connected.

== Can udev automatically mount partitions or cd drives it finds? ==
- No. There are specialized programs for this, like `gnome-volume-manager`.

nice, but they are absolutely harmless. This will be fixed if there will be a
person willing to fix it ;)

- Set `udev_log` to "info" in `/etc/udev/udev.conf` to improve verbosity of
