Thanks for the reply. This is a brand new Sensebender GW hooked up the a Win10 machine with USB. Any time I insert a USB device there is a normal beep indicating connection. With the new GW inserted there is no beep and when I check the device manager it doesn't show a serial or any other type of device. I've checked continuity of the USB to the SAMD chip and confirmed a good connection. Anything else I should try? The board has a QC Passed sticker and I haven't installed a radio or anything else yet. I was just wanting to use this as a serial gateway.
