Hi,

Our customer report that there is one waring log in windows logs. Please check below message.

The O.S. is windows 8.

------------------------------------------------------------

Log Name: System
Source: Win32k
Date: 6/13/2013 6:18:02 PM
Event ID: 264
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: test
Description:
A multi-touch device reported inconsistent contact information.

------------------------------------------------------------

But

(1) The multi-touch device has passed the WHCK. And,

(2) we also double-check it the device hid descriptor. Device pass the descriptor check by Microsoft's tool "Digitizer Report DescriptorChecker".

I know there are many laptop have the same problem. But no one has solution for this.

Did MSFT has solution for this or any other test tool which can help to find the root cause? Since the log is created by System, and our device alreay check our all functions which declared in the hid descriptor. We have no idea why the waring showing up.

Once MSFT reply the event id 264 issue by the following return information.

MSFT : it may relate to firmware. For example, firmware claims it can support 2 contacts, but actually it reports 5 contacts information.

But We can't find the wrong part of our device's hid report descriptor, and device alreay pass WHCK. Since many other laptop have same problem, I think it's not a easy guess root cause by checking our own firmware. Hope MSFT can check this issue and offer more information.

From the event id 264 description:
A multi-touch device reported inconsistent contact information.

We would need more "precise" reason of the warning log.

Best Regards,

Sean
