Can't connect to Arduino

Hi folks -
recently unpacked my M2 that had been in storage. It was working before. Now Makerverse will not connect to the Arduino at all.
Things I have checked

  • power is on, have a green light
  • replaced USB cable
  • tried every usb-c port on my MacBook
  • tried every port I can in Kerverse, which really seems to be only two - URT1 or URT2. don’t recall which it was using before
  • downloaded and attempted to install DUE firmware update, but this also fails as Arduino IDE is unable to find the device.
  • pulled the DUE off and reconnected, made sure everything was clean and plugged in.

Any ideas? Nothing seems to be able to speak to the DUE , either Makerverse or Arduino IDE. So I’m stuck.

Thanks !

Having the same problem ! Did you ever figure out what the problem was ?

Ultimately what fixed this was Makermade sending me this driver :

Which allowed the MacBook to see the Due
Hope that helps,

I am using a Win 7/10 system to run my setup, not an Apple . I will check the link thanks.

are you using the correct USB port on the m2 controller?
