I am writing on the USB device.I am sending data from SBC2440 III and receiving it at desktop pc.I am using OpenNetCF.Serial.dll to perform read and write operation.I have installed active sync on the desktop machine and I can read data only when the active sync is connecting.For reading the data,I am using Device Monitoring Studio 6.18.When the active sync is connecting ,I can receive packets in Device Monitoring Studio.Once the connection is established between SBC 2440 III and desktop device ,the read operation stops.I want to read data continously.
