[Stephane Klein <stephane@harobed.org>]

Hi,

I've a simple question : What Debian use to detect hardware component ?
Example, my system load automatically a Ethernet driver module. Who load 
this ? The discover program ?
If yes, I see discover program is old, 
https://alioth.debian.org/frs/?group_id=30273

On my Ubuntu system, I haven't discover package installed on my system. 
What Ubuntu use to automatically load kernel module ?

Thanks for your information.

Regards,
Stephane
