Retrieve raw data from HID device

Question

Hi, i'm new to windows store app.

I was development a program in desktop which retrieve raw data (HID Report) from HID digitizer device.

However, i meet some problem to porting this program to store app.

After a survey, i know the store app is running inside a sandbox, that is, create and read handle may not work.

In Build 2011 HW-747T, it was talking about connect to specialized devices.

They mention the store app can use DeviceIOControl APIs to communicate with device.

But this needs to develop a special driver.

What i need just only read the HID report, no necessary for write.

So, may i know is there any method or API can make store app retrieve HID report from device?

(without make any changes of the current driver)

And what is the difference of using DeviceIOControl APIs and Windows store device app(WSDA) ?

Can a WSDA bundle a digitizer driver?

Thanks a million.

Hi Alvin,

WSDA cannot bundle a device driver.

However, there may something you can use here - http://msdn.microsoft.com/en-us/library/windows/hardware/gg487435.aspx

Windows 8 requires a driver in order to get access to raw HID data.  This sample illustrates how to do this:  http://code.msdn.microsoft.com/windowshardware/HID-Client-Sample-2e2a6281
