XferData sends data twice
I have a USB device and I'd like to be able to communicate with it. Device uses cyusb.sys driver installed with Cypress Suite USB 3.4.7. Before starting work on my own application I used CyConsole and Control Center both available with 3.4.7 Suite. I tried to send 2 byte data to device. In order to see data transmitted through USB cable I used USBlyzer software. I noticed that data is sent twice to device (see attached picture). CyConsole and Control Center uses XferData method to send data. I have 64 bit Windows 7.
I searched forum to see if anyone had such problem but I didn't find anything. Does anyone knows how to solve this problem?
