USB problem

There is a problem on my MINI2440 kit, the [f] Format the nand flash option
was chosen. This erased the Bootloader parameters table, and the USB port
is no longer being activated. At the beginning it appeared to be a
Supervivi´s problem, however I´ve flashed several versions using JTAG, and
the problem persists.

I´ve activated the port when it stopped working some months ago, because I
found the procedure on the web, this is how I know it´s possible. I think
it´s just a matter of adding the USB port to the bootloader parameters
table.
