Really Plug & Play?
 

Hi,
I know that PnP (plug and play) is a feature at hardware level, which let device to set it's port number, interrupt, and other level settings.
Know I want to know if it's a problem with PnP feature under Linux that it need every devices to be mounted first. You know even using USB technology you have to mount your USB drive forst.

Thanks in advance.

This post should really be in hardware, but Ill answer anyway.
Mounting has nothing to do with PnP. PnP still sets up the drive, and
configures it, yet, it still needs to be mounted to be part of the filesystem.
This is not a problem, its more of a feature. Not all USB devices need to be
mounted, only storage devices. My Ti83 Calculator link cable sets itself up fine,
as does my mouse. If you want your USB drive automatically mounted, you could
try writing a shell script that periodically checks for its existance, or use SuSEplugger
which automatically mounts devices, although you have to be using SuSE.

I think you can automount an USB-flash drive (or digital camera for that matter) using the "hotplug" package.
