Hello,
My Arduino is not seen by the arduino ide anymore. I've probably set a mess in the system. Can anyone tell me how to check if the usb serial driver for arduino is correctly installed?
Thank you in advance!
Hi @Renaudp. Make sure the USB cable is completely plugged into both the Arduino board and the PC.
If that doesn't help, you may have a damaged/defective or charge-only USB cable. Try a different cable.
Either of the above can result in the power connections being made (and thus LED lights on the board), but no data connections (and thus no port for the board).
If that doesn't resolve the problem, please tell us which Arduino board you are using (e.g., "Uno").
I have tried with different cables: same problem. I am using an Arduino Uno Rev3.
When the board is connected, it's powered because the led is on.
I am more thinking about a driver issue. I have no idea where to check if the driver is properly installed on Apple Ventura.
OK. The USB cable is a frequent cause of missing board ports, but not the only one.
Please try this procedure to check whether the port is recognized at the operating system level:
NOTE: These instructions will not solve the problem. They are only intended to gather more information which might provide a clue that eventually leads to a solution.
- Unplug the USB cable of your Arduino board from your computer if it is currently connected.
- Click the Apple logo on the left side of the menu bar at the top of the screen ("Apple menu").
- Select "System Settings..." from the menu.
- A "System Settings" window will open. Click "General" in the menu on the left side of the window.
ⓘ You may need to scroll the menu down to see "General". - Click "About" on the panel at the right side of the "System Settings" window.
- The "About" panel will open. Click the "System Report..." button at the bottom of the panel.
- The "System Information" window will now open. Select Hardware > USB from the tree on the left side of the window.
- Take note of the contents of the "USB Device Tree" panel of the "System Information" window.
- Plug the USB cable of your Arduino board into your computer.
- Select File > Refresh Information from the menu bar.
Do you see any new device appear in the "USB Device Tree" panel of the "System Information" window after doing the last step?
In the USB Device Tree, nothing is displayed with the uno. When I plug an external disk, I can see it. I have tried with another Uno and still nothing...
OK, so this rules out the possibility that the problem was specific to Arduino IDE.
The fact the problem occurs with two Uno boards suggests it is not a hardware or firmware (the firmware on the Uno's USB chip) problem. It is still possible that both boards were damaged in the same way so I wouldn't absolutely rule that out.
But I think it is worth focusing on your original suspicion that it is a problem with the configuration of your system. Unfortunately I am not very knowledgeable about this subject as it applies to macOS systems. In my limited experience, Arduino boards are "plug and play" on macOS machines, not requiring any system configuration as is sometimes the case on Windows and Linux. So I'm not sure how much assistance I can provide from here, but some of the other forum members may be able to help.
It will be useful for us to know which USB to serial adapter chip your Arduino board has. This is a black chip near the USB socket.
The chip will usually be identified by writing on the top. This might say something like "Atmel MEGA16U2" or "WCH CH340G" or "SILABS CP2102" or "FTDI FT232RL".
Examples:
Microchip ATmega16U2
WCH CH340
FTDI FT232R
If it isn't clear, alternatively you can provide the link to where you bought the board from and we'll see if we can determine the chip from the product listing.
IIRC there are older reports about the CH340 chip on Apples.
My knowledge on apples is also limited.
Maybe a forum search will turn up some results for you.
After reinstalling the system, it's now working fine. Thank you for your help!
