I've just recived an ADuM4160 Evaluation board v1.1 but it seems that this doesn't work properly. I expect a plug&play behavior when I connect the PC-host to USB-B connector and a simple microSD reader from the device side (USB-A connector). I've checked jumpers configuration but I think everything is ok. All of them are placed as default. Summarizing, the microSD are not detected by the PC-host. I also tested the board with others USB devices with no success. What could be wrong with my Evaluation Board?
