Hi everybody

I'm trying to read an external I2C 24LC256 eeprom content using a FT2232D connected to the computer with USB
I have a very old (2007) c++ application that works and I can see the signals with a logic analyser (az delivery + saelae)

But when I try to do it with a new c# code, it fails. Here is my code to read 32 bytes

using Iot.Device.Ft232H;
using Iot.Device.FtCommon;
using System.Device.I2c;
....
Ft232HDevice ft232h = new Ft232HDevice(FtCommon.GetDevices()[0]);
I2cConnectionSettings i2cSettings = new I2cConnectionSettings(0, 0xA0);
I2cDevice i2cDevice = ft232h.CreateI2cDevice(i2cSettings);
byte[] b = new byte[32];
i2cDevice.WriteByte(0);
i2cDevice.WriteByte(0);
i2cDevice.Read(b);
Console.WriteLine(BitConverter.ToString(b));

When I look the logic analyser, there is no signal between the FT2232D and the EEPROM
It would be great if someone could give me any idea to fix this...
Thanks
