If You want to pay:

and if you have a computer w/out administrative priveladges get: Geoshell. Its a utility that allows you to have administrative access on computers that dont allow it. (i used it on a school computer and viewed the hard drive even thouh you can't without administrative access.)

Good Luck!

is a comercial product (you have to pay for, thought not to much)and might be the thing you are looking for.

The company is called encryptx or so. Google for it.

But note: this is just a joke, event the little money they are asking for is too much for it in my opinion. It does no encryption, so all files are still here in their full beauty for everyone to be seen , copied , modified etc.

I am just curious: why do you need an extra password to be entered when you have no intention to protect something, or to expect any function of that password at all?

In such case, you might also call with the autorun.inf some batchfile simply asking you to enter a password.

This an't open source, but at least it's free.

You can use Rohos Mini Drive (I recently found and started using this.) It provides encryption but explicitly states that you do not need an administrative account to access your files.

It doesn’t require Administrator Privileges to open password protected USB drive partition!

My Brief Overview:
You first install the program on your harddrive.
Next, you follow a wizard to setup your portable drive (no files are deleted).
Then, you can move all your portable apps or encrypted stuff into the encrypted section.
What is fantastic is you don't need to install any other stuff on your harddrive once the usb is setup, there is a pretty little app to unlock your stuff inside the usb.

I couldn't find an autorun function so I hijacked the portable app one:

[Autorun]
Open=RohosMini.exe
Action=Unlock encrypted files.
Icon=RohosMini.exe
Label=Lexar
