I used many Arduino boards without problems before. Not sure what I'm doing wrong. Windows 10, connect USB port and COM3 shows MKR1000, Windows shows the device. Appears and disappears as expected when connected and disconnected. Arduino IDE 1.6.9, Board installed via board manager and selected. Libraries WiFi101 installed. Hit upload as usual and it says no device on COM3 after compiling. Board info yields: BN: Unknown board VID: 0403 PID: 6001 SN: Upload any sketch to obtain it
Tried several different sketches and they won't upload. Now what?
