I've made to transfer data from PC COMBLOCK by the above code on channel 2 and got the right result. However, I encountered a problem. When I want to send a string of 3 to 0 using the code below, then the error message when running the application WinUSBsampleApp "Timeout reading from USB devices. Error 997". I've been thinking a lot but still do not understand why this is so.
