read and writing PS/2 mouse device.
I would like to write a userspace driver that can talk to the PS/2 touchpad that I am connected to. I know that mice are typically input only - but I need to send a command sequence to the touchpad to initialize it .
I have been trying to read and write from/to /dev/input/mouse2. I can read and write to the device file, but the results are the same with the touchpad connected or not. The response from /dev/input/mouse2 show ACKs for each write, but my sniffer shows no traffic.
Can you direct me to some place that may offer some help?
