You can't. On Windows every device needs a (device) driver in
order to work. You either have to install the manufacturer's device
driver or the one provided by libusb-win32.

From your application's point of view it should make no difference
whether you install libusb as a filter or as a 'normal' driver. 
You get the same API and the same functionality. The only difference
is the way the kernel driver (which is the same binary file in both 
cases) is installed.
