+PLD udev FAQ (udev-0.71-5)
+--------------------------
+1. Which kernel version is recommended for proper work of udev/udev-hotplug?
+   
+   *Minimum recommended version is 2.6.12.x* (udev hotplug won't work with the older)
+
+2. Udev doesn't load all modules for me!
+
+   ...that's because it loads only modules for PCI devices that meet the requirements
+   included in udev rules. That rules allow auto-loading feature only for internal
+   USB devices (hubs), such as uhci-hcd or ehci-hcd.
+
+   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.
+   
+3. 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
+   hotplugs is uninstalled.
+   USB pendrive will work like a charm if you read answer no. 1.
+   
+4. 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.
+   
+5. Can udev automatically mount partitions or cd drives it finds?
+
+   No. There are specialized programs for this, like gnome-volume-manager.
+   
+6. I'm using nvidia-legacy and the /dev/nvidia* is not created!
+
+   That's a problem of nvidia (legacy) drivers. udev has nothing to do with it.
+   Unfortunately, you must manually create proper device files using mknod.
+   
+7. I have to manually load modules such as psmouse or evdev! Why?
+
+   The kernel's input layer is broken. It's said to be fixed in 2.6.15...
+   
+8. Do I have to add the usb-controller alias in /etc/modprobe.conf?
+
+   No. All *-hcd modules are loaded automatically.
+   
+9. I get the error messages about failed agents in my system's logs!
+
+   They don't work because they are not there - unless you installed udev-digicam,
+   which has the usb agent. That udev warnings in logs don't look nice, but they
+   are absolutely harmless. This will be fixed if there will be a person willing
+   to fix it ;)
+
+10. I've got a problem which is not covered here. How do I diagnose it?
+   
+   Set udev_log to "info" in /etc/udev/udev.conf to improve verbosity of udev,
+   use udevmonitor (man udevmonitor) to get even more infomation, check the
+   linux-hotplug list's archive http://marc.theaimsgroup.com/?l=linux-hotplug-devel.
+   If still unsure, ask your question on PLD mailing lists.
