Remarks

The HID class driver uses an IOCTL_HID_GET_DEVICE_DESCRIPTOR request to obtain a device's HID descriptor from a HID minidriver.

For information about HID descriptors, see the Universal Serial Bus (USB) standard Device Class Definition for Human Interface Devices (HID) located at the USB Implementers Forum website.
