I'm trying to use the Summagrid V(tablet for digitizing) on Debian "Etch" but I couldn't make it comunicate to the serial port. I've already installed the drivers for Summagraphics tablets from X.Org but it didn't work. I tried to change the switchs(located inside the tablet) and installed the driver for calcomp but, again, nothing happened . If anyone passed for a problem like this and have any information to help me, please let me know.
