So I have an 8 channel SPDT USB ProXR Relay Controller but it wasnt working. So I bought a 16 channel ProXR Relay Controller however I didn’t purchase a new ZUSB. I’m still using the same ZUSB and also the new 16 channel relay controller. When I connect the Mini USB from the 16 channel relay controller to my PC, the TX and RX LED lights light up 4 times and then go off and the USB LED light doesn’t flash at all.
I’ve tried updating the driver by following the guide on http://www.ftdichip.com/Drivers/VCP.htm and that didn’t work either. I am leaning towards the idea that this ZUSB module interface is malfunctioning. Does anyone have any ideas?
