Since you have a working driver, you can: 1)Identify the events begin emitted from your input device using: "cat /proc/bus/input/devices" 2)Capture the data from the input device using: "ls /dev/input" to find your device's event output then "cat" the appropriate file for the actual data.
You may have to look at the driver to understand what type of events are being sent(read: https://www.kernel.org/doc/Documentation/input/event-codes.txt). If you're lucky, you'll get absolute events being sent or relative events with a known origin position. This is all speculation though from a little online research. Good Luck!
