How I create a Virtual Tokens for my aplication?
The Firefox have 4 ikeyVirtualReaders used for update and detect when a new
usb token is inserted or removed from usb port.
How I can do it too?

The iKey virtual readers are features of a PKCS#11 module offered by the
maker of the iKey token products, IIRC.

If you examine the list of PKCS#11 software modules in your FireFox
installation, you'll find information about that PKCS#11 module there.
Tools --Advanced (tab) -Security Devices (button)

Your application simply needs to have access to that same PKCS#11 module.
Your application may have its own UI for configuring PKCS#11 modules,
or it may use the NSS command line tool "modutil" for this purpose.
