Hi Paolo, Not sure if this could be the culprit of your problem, but the Raspberry Pi has some serious USB issues depending on which kernel and kernel parameters you are using. I've had similar issues with other USB devices, especially a FTDI USB-RS232 converter.
Try running a "BRANCH=next rpi-update" and take a look at this thread: http://www.raspberrypi.org/forums/viewtopic.php?t=70437&p=510566 Regards, Martin Hejnfelt _______________________________________________ fprint mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/fprint
