I cannot connect my Arduino UNO to my Macbook Pro. In the online editor, there is a little line with a red cross next to the box where it shows the board model. And in the IDE there is no USB-port in the port-menu, only bluetooth and serial 1/2. I have tried everything now, went through every single "solution" in different forums.
I've been downloading other drivers (the CH340, CH34x etc. for the fake/china boards), although I'm quite sure that my board is genuine.
I've been installing loads of other software and weird drivers.
I've been trying the whole thing on a Windows computer as well.
Do you have any idea what is wrong? I'm about to give up.
Thanks in advance.
