usb camera / filesystem question

[Christian Convey <cconvey@cox.net>]

Hi guys,

I'm curious about the way a USB camera gets set up when plugged into a 
Sarge / 2.6.9 system. I'm also using 'udev'. Anyone know the following?

When I plug in the camera, I assume there are three devices that must be 
created in the /dev directory, no?

#1 : a device for the camera's plain old USB interface (i.e., ttyUSB1)
#2 : a device for the camera as a usb mass storage device (i.e., sda)
#3 : a device for the partition on that storage device (i.e., sda1)

Can anyone tell me which pieces of software are responsible for setting 
up each of those devics?

Thanks,
Christian
