I've perused the forums and done some troubleshooting on my own, but I'm out of ideas.
ISSUE:
My new Arduino Nano 33 BLE is not detected by IDE. When I go to tools -> ports, there is nothing there, other than bluetooth. It's simply not detected.
The orange light is blinking properly (1 second intervals).
ATTEMPTED SOLUTIONS:
-Try new USB cable
-Try different USB ports
-Try connecting to my Macbook, multiple ports
-Try connecting to my Windows desktop, multiple ports
-Check connectivity with my Arduino Uno. It works perfectly.
-Perform every permutation of of unplug/plug in, quit/restart, reboot.
-Double Click button on Nano (Which yields the pulsing light)
-Rollback IDE Nano drivers in board manager (From 3.0.1 to 3.0.0)
Any advice, or perhaps simply a death certificate, would be much appreciated.
I know that you mentioned that you tried another cble but try a third one. On boards with a micro USB connector, the cause is often the use of a charge-only cable that does not carry the data signals. If you have any other device (e.g. phone) that uses a micro USB connector, check that the cable allows your PC to detect the device.
Now of course it's having problems with the sketch I'm trying to upload, but that's a different post, for a different category, for another time. For now: great victory!
