HID input from a sensor driver?

Question

Hi again.

I am trying to create a sensor driver for a device that is normally accessible through HID. However it seems that HidD* functions are not available for UMDF, for example HidD_GetHidGuid , HidD_GetPreparsedData are not available in the hid.lib. It seems that I can't also use raw input with WM_INPUT .

Do I have any other option ?

Answer 1

Hi Michael,

Have you looked at the Sensor Development Kit sample driver (can be downloaded from http://code.msdn.microsoft.com/Project/Download/FileDownload.aspx?ProjectName=SensorsAndLocation&DownloadId=5856)? That driver communicates with the board which connects through HID. In essence, you would be reading/writing requests from the lower driver on the stack (which in this case will be HID) rather than using the HID APIs directly.

Thanks,
Prasanna

Answer 2

So you 'd say that I need to CreateFile() the HID device from the UMDF driver and read/write with normal I/O ?

Edit: I did that and it worked - thx.
