Routine Description:
This routine retrieves any non-present devices matching the specified
criteria, and returns them in a device information set.
Arguments:
Enumerator - Optionally, supplies the name of the Enumerator under which
this device may be found. If the device may show up under more than
one enumerator, the routine can be called with Enumerator specified as
NULL, in which case all device instances in the registry are examined.
HardwareID - Supplies the hardware ID to be searched for. This will be
compared against each of the hardware IDs for all device instances in
the system (potentially filtered based on Enumerator), present or not.
Return Value:
If any non-present devices are discovered, this routine returns a device
information set containing those devices. This set must be freed via
SetupDiDestroyDeviceInfoList by the caller.
If no such devices are encountered (or if an error occurs), the return
value is INVALID_HANDLE_VALUE. GetLastError will indicate the cause of
failure.

* Finds information about USB HID devices using setup class API.
*
* The sequence of entries in array must match with what java layer expect. If a particular USB
* attribute is not set in descriptor or can not be obtained "---" is placed in its place.
*
* The array returned will be in following sequence; transport, device node, vendor ID,
* product ID, serial, product, manufacturer, USB bus number, USB device number, location.
*
* For an HID interface in a USB device, Windows create a device instance for the USB interface
* (GUID_DEVINTERFACE_HID_DEVICE) and another device instance for the HID collection (GUID_DEVINTERFACE_HID).
* This function relate HID collection device instance to its USB interface (physical USB device) through
* HardwareID. A hardware ID is a vendor-defined identification string that Windows uses to match a
* device to an INF file. In most cases, a device has associated with it a list of hardware IDs.
* (However, there are exceptions − see Identifiers for 1394 Devices). When an enumerator reports a
* list of hardware IDs for a device, the hardware IDs should be listed in order of decreasing suitability.
*
* This key contains symbolic links to HID device instances :
* HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{4d1e55b2-f16f-11cf-88cb-001111000030}
*
* This function basically collect information from USB and HID subsystems and relate them to identify a device
* and then create a unified information to be sent to java application.
