- creates an instance (USBDeviceList) initialized to null of the class CCyUSBDevice
- reads and displays the number of Trenz Electronic modules (TE_USB_FX2_ScanCards())
- selects the first (0) Trenz Electronic module;an handle to the device driver is open but not exposed to the user
- reads and displays VID and PID of the selected module
- reads the firmware version of the selected module
- selects the second (1) Trenz Electronic module;the previous handle is automatically closed and another handle (this time associated with the new Trenz Electronic module) to the device driver is opened but not exposed to the user. If the selected module is not attached to the USB bus, the previous handle is automatically closed but a new one is not opened.
- reads the FPGA firmware version of the second (1) module
