Which OS?
What does your OS think about the board? In Linux I would look at dmsg and lsusb and (from memory) /var/log/messages.
Did the board ever work?

Do you get the same thing when it is disconnected? What operating system are you using?

Hello,
I use mac high sierra on a mac.
Arduino boards are generally not recognized as an eternal disk.
The card has already worked with another computer that I don't have. :roll_eyes:

If you add that info to the title of your topic, the topic might get the attention of those more experienced with a Mac.

I have install the driver for the arduino nano. Now works! :smiley: Anyway thanks for the help! :handshake: :wink:
