Hi,

I hope this is the right list for my question -- if not, please help me 
finding the right destination.

I have a Sony Vaio Duo 11 where the middle mouse button does not work.

The device in lsusb is listed as:

Bus 001 Device 005: ID 26e1:c1a0

Greping through the kernel for device IDs I do not find a driver in the kernel 
that is explicitly written for that mouse. So, I expect the generic USB mouse 
picks this device up.

The input framework knows the device as:

/dev/input/event3:      Crucialtek co.,LTD Optical Track Pad

The problem now is that the middle mouse button does not seem to be activated 
at all:

- xev does not record any events

- playing around with debug modes of the sony_laptop does not indicate that it 
records any events for special keys

- using usbmon to sniff the raw USB events does not show any events being 
communicated when pressing/releasing the middle mouse button

Note, the right and left button work flawless.

As I am out of ideas. Does anybody have an idea on how to identify where the 
problem is? Would I need to send some "enabling" events to the mouse before it 
activates the middle mouse button? Or is there anything in Linux that could 
help me debug the situation?

As a side note: initially there was Windows on the box. And the middle mouse 
button worked on it. So, the hardware should have no problems.

Thanks a lot
Stephan
