I completed the instructions on the Wiki.
There was no hint how to verify if the burning was correct or if the hardware 
was destroyed
after modifying the board. I was very irritated by this.

Call "usrp2_probe" to check if the board ID is 13 now. If it is still 2, the 
burning had no effect.
I tried two times without success (didn't know that the ID would have to 
change).
After another 3rd attempt later, I was successful.
Very strange. Every time I followed the instructions exactly the same.
