I had my MKR1000 connected to my Windows 7 PC but am having issues all of a sudden (there were a few updates to my Arduino IDE but not sure that's related).
When I plug in my MKR1000 to my USB port, Windows shows an "Unknown Device" in the Device Manager under "Universal Serial Bus Controllers." When I try to manually update the drivers (pointing to C:\Program Files (x86)\Arduino\drivers), Windows just states "The best driver software for your device is already installed" and the device is still listed as "Unknown Device."
I've tried plugging the MKR1000 into my USB port as well as a USB 2.0 hub. Same results.
Any help would be greatly appreciated. My Uno board works fine.
