Is there a software development kit available? Just some simple functions that I could include to read/set the inputs and outputs? It seems clunky to let your software run in the background and send commands through that. :S

Well currently, the program interfaces with a dll provided by Microchip. That dll is free for anyone to use, and it is really really simple to implement. Basically, just call the open port, command, send the stream, receive the stream, and close the port, and then you have sent and received a coded 64byte packet stream. Decoding it is relatively simple. That is the only way right now.

However we do have a volunteer doing some work on coding a general dll. So it would be your code --> his dll --> microchip's dll --> hardware, so instead of encoding/decoding packet streams, all you have to do is tell which port is what.

I thought you were putting together a DLL that would simplify all of that into one COM DLL?... So I didn't have to use that poorly thrown together one that I built for StreetDeck, which reminds me, I need to finish that :P

I was doing it. And I failed at it. I am not very good with writing dlls. I never was able to get shared memory working. However we do have someone who volunteered to help out, and try to get the dll working. He was making great progress on it last I heard. So it is coming hopefully, just not by myself!

Awsome... I really want to get the StreetDeck mod working but the DLL's just dont play well at all with it... now

this is all that is needed to call the device (C#):

Code:

public static class FusionUSB
        {

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern bool FUSB_Initialize(ref UInt32 pFusionUSB, String deviceID, UInt32 instanceNumber);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern bool FUSB_Receive(UInt32 pFusionUSB, byte[] buffer);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern bool FUSB_Send(UInt32 pFusionUSB, byte[] buffer);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern UInt32 FUSB_Free(ref UInt32 pFusionUSB);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern bool FUSB_printf(UInt32 pFusionUSB);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern UInt32 FUSB_GetWinUSBerror(UInt32 pFusionUSB);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern UInt32 FUSB_GetFUSBstatus(UInt32 pFusionUSB);

            [System.Runtime.InteropServices.DllImport("FusionUSB.dll")]
            public static extern String FUSB_GetDeviceInstanceID(UInt32 pFusionUSB);

        }

The easiest way is to initialize first by passing in the device ID and getting a pointer. Then just use send (byte[64]) and then receive which returns a byte[64]. When you are done call Free with passing in the pointer.
