USB Slave | How to setup internet for Angstrom

Hi,

New to embedded and linux in general. Learning something new with the
device everyday.

I recently succeeded setting up the mini2440 with OE/Angstrom and
Qt4.3.6-Emb. I have also setup Qt creator to compile binaries for the arm
board.

I was wondering if anyone can give me pointers on how to use the USB slave.
I would like to use it as a USB mass-storage device (like how one connects
a phone to upload images, text, etc...).

Also, how does one find what HCI (Host controller interface) the board is
using. I tried running 'lcpci -v | grep HCI' but it gave an error 'lcpci:
command not found'.

One more thing, I can't figure out how to setup direct internet access from
the board. LAN works (I use VNCVIEWER to see my Qt apps), but whenever I
try to install packages using opkg, it says there is no connection. Anyone
know what the problem is and how to setup internet access?

Thanks
