Hi, Damjan, Latest X1 Carbon system has two TrackPoint venders. One is Alps, the other is Elantech. ( Touchpad is only Synaptics.) To detect the device, we can send "E1" command by using pass-through. The device response is as below. If Alps, E1 -> 02 If Elantech, E1-> 01 It's a spec, but I have not checked it. By the way, TrackPoint speed might be different between Alps and Elan. And Middle Button Click behavior without a driver is the same as Mouse middle click.

Is there anything else I can test? -- damjan ��.n��������+%������w��{.n�����{��)��^n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
