I have two logomatic boards and two (freshly FAT23 formatted) 16GB microSD cards. I've followed the hookup guide.

When I connect the logomatics to my PC via USB the 'charge' and 'USB' LEDs light up and stay on. No data is written to the SD card, in fact I get the same behavior with no SD present. Besides the fresh SD cards I have tried some older and smaller 1GB cards (freshly formatted).

Please could someone point out what I'm missing?
