DLL version GHI is 4.3.3 and MS is 4.3.1 is this correct?
@ David@ Emrol -
Can you please use a different SD or try to format that SD?
If you are using FEZ CorbaII then the connection should be OK (no wire needed) but if using a FEZ Spider II or custom board, make sure the connection board and SD is good.
If i deploy my main application to the custom board then this is reading startup config from this SD and logged data to SD so connection should be ok.
To be 100% sure i just put a brand new quality SD in but same result.
More things that i can check?
@ David@ Emrol -
I just ran your code with a bit modified. Yes, sometime I see the exception same as you. But it work fine without VS debugger (I just press Reset button).
But in my old code, it works fine.
Can you please try my code (just copy and paste) or deploy code below and run without VS
public static void Main()
{
GHI.Usb.Client.MassStorage MyUSBClient;
GHI.IO.Storage.SDCard MySD;
MySD = new GHI.IO.Storage.SDCard();
MyUSBClient = new GHI.Usb.Client.MassStorage(0x1B9F, 0xF002, 0x100, 250, "TriNeuron", "MFC", "123456", "xyz", 1);
GHI.Usb.Client.Controller.ActiveDevice = MyUSBClient;
Thread.Sleep(100);
MyUSBClient.AttachLogicalUnit(MySD, 0, " ", " ");
Thread.Sleep(100);
MyUSBClient.EnableLogicalUnit(0);
Thread.Sleep(-1);
}
Correct! if i press reset then the SD get’s mounted, from VS i have the error.
Is your original sample running when deployed from VS?
If so then i have a deeper look at this code.
@ Dat - I tried your sample code but in debug mode i have the same error.
If i reboot the custom board with code bellow the SD gets mounted.
However i copy that exact lines in my main program it fails.
More ideas?

@ David@ Emrol -
See, now I can reproduce with VS in my side. I will find if there is any workaround.
I have been playing some more in my main application and have different errors if i change the sleep time at the marked line bellow:
//4.3 connect only once !
if (USBControllers[0].Status == Microsoft.SPOT.Hardware.UsbClient.UsbController.PortState.Running && MyUSBClientLoaded == 0)
{
// only if SD is active
if (SDStorage != 0 )
{
// flag
MyUSBClientLoaded = 1;
// log naar syslog
SysLogFileWriteLine(RealDateTime + " : " + "USB Client connected");
// still mounted -> close all file handles
FreeSDcard();
Thread.Sleep(50);
MySD.Unmount();
while (MySD.Mounted == true)
{
Debug.Print("waiting on release SD...");
Thread.Sleep(50);
}
try
{
//4.3
MyUSBClient = new GHI.Usb.Client.MassStorage(0x1B9F, 0xF002, 0x100, 250, "TriNeuron", "MFC", "", "", 1);
Thread.Sleep(100); // <<<<<<-------- THIS SLEEP TIME
GHI.Usb.Client.Controller.ActiveDevice = MyUSBClient;
Thread.Sleep(100);
MyUSBClient.AttachLogicalUnit(MySD, 0, " ", " ");
Thread.Sleep(100);
MyUSBClient.EnableLogicalUnit(0);
}
catch
{
MyUSBClientLoaded = 0;
SysLogFileWriteLine(RealDateTime + " : " + "Error at attachlun(0) and µSD");
}
}
}
I first noticed different errors if i was stepping in code or moved my breakpoints.
With the 100ms sleep if have this error:
#### Exception System.ArgumentOutOfRangeException - CLR_E_OUT_OF_RANGE (4) ####
#### Message:
#### System.Collections.ArrayList::get_Item [IP: 0000] ####
#### System.IO.FileSystemManager::ForceRemoveNameSpace [IP: 0026] ####
#### Microsoft.SPOT.IO.RemovableMedia::MessageHandler [IP: 005c] ####
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll
If i increase the sleep time to 1000ms i have:
#### Exception System.InvalidOperationException - CLR_E_INVALID_OPERATION (8) ####
#### Message:
#### GHI.Usb.Client.Controller::NativeStart [IP: 0000] ####
#### GHI.Usb.Client.Controller::set_ActiveDevice [IP: 0018] ####
#### IRC.Program::WDTCounterResetLoop [IP: 0151] ####
A first chance exception of type 'System.InvalidOperationException' occurred in GHI.Usb.dll
An exception of type 'System.InvalidOperationException' occurred in GHI.Usb.dll and wasn't handled before a managed/native boundary
Annyone has a deeper knowledge understanding what’s the possible root cause?
The fact that deppending on delay the error ocures in a different dll makes me think there is still some init process running but i dont see a way to check a “ready” state in a delayed loop…
