shall be used. Cypress sets DesiredValue to 4,096 bytes by default. This default value is not documented in the CyUSB.dll manual (pag 110-111 of CyUSB.NET.pdf), but it has been retrieved by using the following C# instructions:

int XferSizeReadValue = outEndPointPipeNo.XferSize; |

Console.WriteLine("XferSize {0} ", XferSizeReadValue); |
