Hi Tim, Thanks for your help.
I've finally managed to get it working using "libusb" and the protocol specification at http://pegatech.blogspot.com/2009/01/communicating-with-tablet-mobile.html I don't know if it's worth writing a device driver for it, because my small application with libusb works quite well. I may want to take a look at device drivers, though. Thanks again, Antonio -- This message posted from opensolaris.org
