I have a very old RS232 serial tablet (an AceCad III). It does work in Ubuntu, because I've been able to get it to work by disabling hotplug in the X server, but I'd rather leave input device hotplug enabled.
It seems like an InputClass section is what I want. My question is, how do I get the X server to recognize my serial device (it obviously can't autodetect it)? I tried
inputattach --dump /dev/ttyS0 but X didn't seem to pick it up (nothing in the log files).
For reference, here's the InputClass section I'm using:
Section "InputClass" Identifier "AceCatIII" Driver "mouse" MatchDevicePath "/dev/ttyS0" Option "Protocol" "AceCad" Option "Device" "/dev/ttyS0" EndSection
I'm on a fresh install of 11.10.
