// The HIDFAKE sample driver uses feature reports for out-of-bad communication
// between an application and the driver. This file, which is shared between
// the user-mode test applet and the driver, defines the format of the feature
// reports.

// Dummy VID/PID values to simplify test applet's scan. You *must* use your own
// unique values here, or else you'll likely collide with some other vendor's
// fake HID device.

#define HIDFAKE_PID		0x5678
