Reports

Commonly you can get the data with these usage id and pages from microsoft :

Member  Description                         Page    ID      Mandatory/Optional
X       X coordinate of contact position    0x01    0x30    Mandatory for T Optional for C
Y       Y coordinate of contact position    0x01    0x31    Mandatory for T Optional for C

X/Y

The X and Y values report the coordinates of a given contact. A Windows Precision Touchpad should report one point for each contact. The following global items should be specified for both the X and Y usages:

Logical minimum & Logical maximum (ensuring greater than or equal to 300DPI input resolution).

Note  The entire logical coordinate range should be reportable across both the X and Y axis.

Physical minimum & Physical maximum (see Device Integration - Size).

Unit & unit exponent.

The coordinate 0,0 (x, y values) indicates the top left corner of the touchpad.

Coordinates are in array if valueCaps[i].UsagePage = 1 and valueCaps[i].NotRange.Usage = 0x30 (x), valueCaps[i].NotRange.Usage = 0x30 (y)

xLogicalMin, yLogicalMin, xLogicalMax, yLogicalMax are in valueCaps[i] array

    xLogicalMin = valueCaps[i].LogicalMin;
    xLogicalMax = valueCaps[i].LogicalMax;
    xPhysicalMin = valueCaps[i].PhysicalMin;
    xPhysicalMax = valueCaps[i].PhysicalMax;

Apparently xLogicalMax, xLogicalMax  are more in line with the parameters of the Touchpad.
