Reply to LEDs not working

Hi all.

I'm the proud owner of a VCI-100SE Arcade Edition wich just came from USA (I live in Argentina).

I've been using the VCI for a couple of hours and noticed that some LEDs (DATA, POWER as well as the FX PRESETS) aren't working at all.

Tried using USB and external AC adaptors, 2 Mac Mini and 1 MBP all with Snow Leo at 32bit and same problem. Tried 4 USB cables too.

Any idea? Using Tracktor Pro 1.2.4 and TSI 3.5.1

Many thanks in advance.
