Hello, I bought an Arduino Starter kit (with the Arduino UNO R3) 1,5 years ago and back then I tried to install it, but had some issues that I couldn't understand at that time and I thought maybe it was because I was too young. But I tried it another 5 times in the past year and I read almost the whole forum that could be relevant to my problem and still couldn't fix it. I have the problem that when I plug in my board and I want to select a port that the serial port is greyed out (on my MacBook Pro M4). I tried to understand what was wrong and used different cables, like printer cables and still didn't work. I also tried different ports of my computer, also didn't work. Also with this command: " ls /dev/cu.* " I found only these 2 ports: /dev/cu.Bluetooth-Incoming-Port /dev/cu.debug-console , after plugging in my uno board. I also took a look at the system information under Hardware and then under USB, and there also didn't change anything when I plugged in my board, so the board really just doesn't get detected. And then on my windows computer, I also plugged in the board and I got right away the notification: "the last usb device you connected to this computer malfunctioned and windows does not recognise it" so that also says it doesnt get detected, I think. I have the Arduino app IDE 2.3.10 installed and that went smooth. So I am really stuck at trying to connect a port, is there something I missed? Does anyone have an idea what I can do to try and fix it? It is a brand new board and not yet used so maybe can anyone confirm that it is probably a hardware problem and that there is nothing to do about it and I just have to buy a new board? Thank you in advance!
Did you ever need to install a non-FTDI driver, one being CH340/CH341 (for your operating system to communicate with the Arduino)?
Not that I know, I searched on the internet and it said that if I have a genuine Arduino board that it was not necessary to install a driver. Because the 2 chips on my UNO R3 board are ATmega328P and ATmega16U2, I thought my MacBook Pro has a built-in support for it. Do you think I should install a driver?
This is true. No need for the other drivers.
In Windows, what does the Device Manager see it as (when USB isninserted)? Do you hear the system chime?
In MACOS, what does it see? Any system chime?
I would suspect a cable problem. USB-C to USB-B is not that common. Where did you source your cable?
In Windows: yes I hear the system chime and in the device manager I see under Universal Serial Bus controllers : "Unknown USB Device (Device Descriptor Request Failed)" and in MacOS: I don't hear the system chime and there doesnt change anything in the System Information, still 3 times "USB 3.1 Bus"
I use the USB-B (from Arduino) to USB-A cable that came from the starter kit and then I ordered a small adapter , here is the link: https://www.bol.com/be/nl/p/sitecom-usb-c-to-usb-a-mini-adapter/9300000153620601/ and this adapter goes from USB-A to USB-C and I tested it by printing and it worked so it is good for data transfer as well.
Oh I am really sorry, I'll adjust it right away.
Would you be able to borrow a data cable with the correct ends to verify the adapter has no effect on communications?
Did you buy the Starter Kit from Arduino or from a third party?
I have a genuine Arduino R3 that I use with an M2 Pro that works fine. The only obvious difference is that I use the Apple USB-C to USB-A adaptor rather than an aftermarket one.
I am not sure if I have that at home but I'll take a look. But when I connect my Arduino to my Windows computer, I don't need the small adapter and there I have also problems with detecting it, so I would think the problem has nothing to do with the small adapter because I don't use it with my Windows computer.
Yes, I bought it from Arduino. Okay, maybe I have to buy that adaptor, but I can print with this adaptor that I have so it should work with the Arduino as well I think.
You could try this
That might be the solution. It should "just work" on the Mac.
I don't know if they are available to you in your country but the Cable Matters USB-C to USB-B cables also work flawlessly with the Mac to Arduino.
If you have a suitable USB hub on hand, it is worth trying that as a substitute for the adapter you are using now.
We do periodically see reports from people having trouble with macOS recognizing their Arduino boards, that are eventually found to be resolved by changing the approach of connecting the board to the computer. Sometimes the reported solution is connecting the board directly to the computer via a cable instead of via a hub. Other times, the reported solution is adding a hub between the board and computer. I haven't ever managed to determine a pattern, and my boards work just fine with my Mac either way. But the most important part is to get the board working. If some adjustment to the connection mysteriously achieves that, then we can at least be happy even if it isn't so satisfying as if we determined an explanation for the problem and solution.
I am not familiar with a USB hub, what kind of USB hub should I get for a MacBook Pro? And if a USB hub doesn't work, I should buy an USB-B to USB-C cable? And do you think it is smart or necessary to do what is suggested in post #14 or after I tried USB hub and USB-B to USB-C cable?
USB hubs allow you to connect multiple devices to a single USB socket on your computer.
The traditional USB 2.0 hubs look something like this:
The USB C hubs typically will provide other connectors like HDMI in addition to USB. For example:
I wasn't necessarily suggesting you buy one. I was thinking you might already have one of these common PC accessories lying around. If so, it would be worth a try just in case it solves the problem.
If you do decide to buy one, there are many available from any place that sells computer accessories. The Apple store will sell models that are verified to work with Macs, but the prices are very high (I'm sure the quality is also good though). You can also get them for a much lower price elsewhere. Some of the random suspiciously cheap models are problematic, so you might be gambling if you buy the cheapest available. There are reasonably priced hubs from well trusted brands.
That doesn't work for me. I get as follows:

Except of course I have never used that link before and I don't have a VPN on my home broadband....
However, was going to ask whether you have tried a different USB cable to the one supplied with the kit?
This is the product from the sales listing at that link:
