need to install a built-in camera in my laptop SONY VAIO

I am new in Linux. I just installed Ubuntu 11.04, and everything works perfect on my laptop, except my built-in webcam, and the SD card reader.
My laptop is a Sony Vaio vgn-Tz25fn, the driver for the camera seems to be Sony Camera VGP-VCC7 Driver.
[for the SD card reader i have no idea].
Sony doesn't stand for linux, it only gives out the drivers for windows, and besides that, i have no idea how to install a driver in linux.
When i run the lsusb command, this is what comes out:
