-/** \brief Function prototype for InstantiateWinUsbInterface routine exported
-  from AdbWinUsbApi.dll
-
-  In order to provide backward compatibility with the systems that still run
-  legacy (custom) USB drivers, and have not installed WINUSB.DLL we need to
-  split functionality of our ADB API on Windows between two DLLs: AdbWinApi,
-  and AdbWinUsbApi. AdbWinApi is fully capable of working on top of the legacy
-  driver, but has no traces to WinUsb. AdbWinUsbApi is capable of working on
-  top of WinUsb API. We are forced to do this split, because we can have
-  dependency on WINUSB.DLL in the DLL that implements legacy API. The problem
-  is that customers may have a legacy driver that they don't want to upgrade
-  to WinUsb, so they may not have WINUSB.DLL installed on their machines, but
-  they still must be able to use ADB. So, the idea behind the split is as
-  such. When AdbWinApi.dll is loaded into a process, it will check WINUSB.DLL
-  installation (by checking existance of C:\Windows\System32\winusb.dll). If
-  WINUSB.DLL is installed, AdbWinApi will also load AdbWinUsbApi.dll (by
-  calling LoadLibrary), and will extract address of InstantiateWinUsbInterface
-  routine exported from AdbWinUsbApi.dll. Then this routine will be used to
-  instantiate AdbInterfaceObject instance on condition that it is confirmed
-  that USB driver underneath us is in deed WinUsb.
