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.
