Re: Sony Vaio Duo 11: getting middle mouse button to work

[Benjamin Tissoires <benjamin.tissoires@gmail.com>]

Hi Stephan,

thanks for the traces.
Well, the device definitively presents an Output and an Input report
on the report ID 2. That means that the windows driver can send and
read configuration to the trackpoint through this report.

I think our best chance here is to capture the initialization protocol
from a Windows virtual machine, and then mimic the behavior under
Linux.

Cheers,
Benjamin
