Reconnection of self-powered device
I have self-powered USB device running on FX2. Everything works except reconnection after USB cable is plugged out. When I plug-in the cable, device is not recognized on the host side and I have to power it down and up again to get it working.
I have implemented VBUS monitoring so device controls DISCONNECT bit. Except for that, what else should be done on the device side when "disconnected" and "connected" conditions are detected?
