I found the object code of the Eazy USB firmware in the firmware directory of the kernel tree (such as the whiteheat firmware). I cannot use it directly however as the USB-RSA does not use the serial port of the AN2131Q but an externally connected ST16C550. Is there source code of firmware for the AN2131Q released under GPL that I can use as role model ?
