Interfacing with the DLL: http://www.mp3car.com/vbulletin/docu...ion-brain.html
The Fusion brain does not use a FTDI chip. It does not produce a virtual COM port. The PIC uses a built in USB controller.
And the DLL that we distribute is a managed wrapper for WinUSB.dll.
WinUSB.dll is a Microsoft genuine driver. There is no extra overhead by using our driver. If you want to interface with winusb directly, go ahead but it is a pain in the ***. Especially handling exceptions/connects/disconnects.
