Install deb from alternate usb

Linux and Unix-Like Ubuntu
1

I installed a command-line system ubuntu 12.04 from usb and that's work.
I don't have a internet connection so what I have to install must come from the alternate usb until I can let work my wireless.
I mount the usb to /media/cdrom but when I do sudo apt-get install xorg , then he ask me for the cd.
I uncommented cdrom on the file sources.list.
What can I do so apt-get find the usb with the alternate?
thanks

Man Page for apt-cdrom (all Section 8) - The UNIX and Linux Forums looks promising.

I found a solution on this website
Add ISO image to apt sources.list
and this works now.
But thank you anyway

I have been using this: Using APT Offline - Using APT and wget

to manually update/install packages offline. works great. you don't need whole .iso
