// [TAG]  		EIP215830
// [Category]  	Bug Fix
// [Severity]  	Normal
// [Symptom]  	CYBORG R.A.T3 Gaming Mouse left/right button has no
// function, instead DPI UP/DOWN config button has left/right click
// function.
// [RootCause]  	We get mouuse button data from constant data offset.
// [Solution]  	Mouse Data should be defining report fields that contain
// modifiable device data.

// [TAG]  		EIP213778
// [Category]  	Bug Fix
// [Severity]  	Normal
// [Symptom]  	Issue with right button on usb absolute mouses.
// [RootCause]  	For the absolute device, it has digitizers page
// (UsagePage is 0xD) or button page (UsagePage is 0x9). We clear button
// data even if it is from button page.
// [Solution]  	Clear the unnecessary bits if the data is from digitizers
// page and return all button data if it is from button page.

// 15    9/04/14 7:42a Wilsonlee
// [TAG]  		EIP183463
// [Category]  	Improvement
// [Description]  	In UEFI spec, the definitions of bits within
// ActiveButtons are EFI_ABSP_TouchActive and EFI_ABS_AltActive, we don't
// support AltActive, clear the unnecessary bits.

// [Category]  	Bug Fix
// [Severity]  	Normal
// [Symptom]  	Usb tip switch data may not be correct if the device is
// multi-touch.
// [RootCause]  	We get the data from the other point, but we only support
// one point.
// [Solution]  	Only get the first point data.

// [Severity]  	Normal
// [Symptom]  	Arrow keys cannot work with specific USB keyboard
// [RootCause]  	HID driver cannot parse a input report that includes both

// data format.
