''I can't detect board'' means I don't see device in ''Available DFU Devices'' box. I try to unplug-then-plug again the USB cable but nothing change. Maybe it is a Win2K problem?
What do you mean by ''I can't detect board'', do you have an unknown device for example. Try to unplug-then-plug again the USB cable an let me know ;-), Regards, STOne-32
