AFAIK we don't switch any LED at all, so this probably is a power problem. What rating has your power supply? Do you use the barrel or USB plug to power the board? I think you need to use the barrel plug for additional load, since the board has some kind of current limitation for the USB connector. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
