usb hotplug and hooking

usb hotplug and hooking

[Oguz Yarimtepe]

Hi,

I want to run an application when an external usb flash disk is plugged to
my box machine that has STLinux installed in it. My aim is to check some
issues on usb disk, whether it has an official software or not. I am not
sure how will i hook my own application that will check usb device
when it is plugged. I don't want the application run at the
background, but run only when a plug is occured.

Will be happy if you guide a little.

Thanx.

Have you looked at writing a udev script? Do you need a GUI?

I will look at the udev scripting. I don't need a GUI, yet. I will
just communicate with the usb device, check its files and if an
authorized software is found (will use asymmetric cryptography) will
load it.  I can write the software that will do the mentioned things.
I just don't know the hooking part. But udev is a good start. Thanks.

I think these days that problem tends to be handled by HAL
http://www.freedesktop.org/wiki/Software/hal and some software listening
to HAL events on dbus . If you are using KDE or GNOME both of these have
tools for automatically running software when devices are detected
(GNOME uses gnome-volume-manager and I think KDE has media://ioslave).

I don't have hald installed at my platform. It is an embedded
platform. Checking the udev rules now.
