I've been working with Nexto for about 2 years with exact same CF card (and camera, if any matter). Suddenly, Nexto doesn't recognize the CF card anymore; in fact, it displays "PC USB", as if it was connected to the computer. I tried to re-plug it to the computer, and then disconnected it again, but it doesn't halp. No matter how I turn on Nexto (not connected to PC and with catd, same but without card, etc.), it always shows the indication for pc connection, and doesn't recognize the card.
I'm using Nexto 2300, V1.03.
