I downloaded the latest version of XCTU and connect an XBee module to the XBIB interface board and connect the board to a computer USB port. I try to detect the model with the XCTU program, and it tells me there is no module. I tried with several modules and several ports, with the same results. However, the XBee white adapter does show up, and that is the only thing that appears to work. Are all the other modules defective or is it a problem with the XBIB-U-DEV? I don't have another XBIB board to try, so how can I know for sure if the problem is with the XBIB board or the XBEE modules or both?
