so that's the brand of it. is there a way to edit your .dll file to operate for a "Alps Glide Point" touchpad?
Well, it's not my dll and I don't really know, but I do know that there is a Synaptics touchpad sdk readily available, as well as some fun little aps like a theremin. I tried the theremin thing on someone's synaptic-less laptop, and it was clear that it would not work. I imagine that, unfortunately for you, these devices are not standard enough to have a generic kind of interface, and it seems that the manufacturer of yours hasn't seen fit to make available tools for developers.
That doesn't mean it's an insurmountable problem, just that I imagine patching together an external for synaptics would be relatively easy, while for other manufacturers, it would require much more low level hacking.
