Hello! UTX! Really agree with you, no jumpers, after today's show, I was thinking of opening it, I decided to do it, and soon realized that there would be jumpers, at least that was done through activation of links in the circuit, another would be through of your NAND, I utima vizita the NAND, I understand, any reference configuration for USB, but I do not remember what it was! That my visit to the NAND, I could not prove the conclusion, the setting, it got a lock on the keyboard, when I gave a check in the system, and ended up losing the Zaurus motherboard which cost me $ 160.00 on a new motherboard! But do not discount the issue of the problem is the software! Know something about this reference to USB in NAND?[size="2"][/size]
