Hardware:

Board: ESP32 Dev Module
Core Installation/update date: Yesterday
IDE name: Arduino IDE
Flash Frequency: N/A
Upload Speed: N/A

Description:

So I am using an ESP32 Dev Module, and a 2017 MBP 13" and after following the arduino installation tutorial for the ESP32 I have the boards, but the ESP32 dev module does not show up as a serial port.

Any help would be great, thanks.

Have you installed the serial port driver?

Please run this command ls /dev | grep tty and paste the result here.

I have not installed any serial port drivers (I think?)

Your board might use USB to UART. You'd need another driver for that.

My ESP32 didn't show up on my MAC either until I installed that driver.

So it doesn't seem like it is installing them on my laptop. The files from the uninstall script are not there.

For MacOS X 10.9 and 10.10, see the folder called "Legacy MacVCP Driver".
It may also help if you drag&drop out the file "Silicon Labs VCP Driver.pkg" to any folder (e.g. Downloads) and start it from there

Well, it crashes my OSX 10.11 machine when I try to upload my sketch (filed a separate issue awhile back, but no answers: #983).

@mistergreen

If your OS X is crashing, it could be because of the USB driver. My OS X crashed when I plugged in my ESP8266.

Hi danthegoodman1. I almost met the same problem with ESP32. Did you figures it out now?

@JohnGEyles
Copy link

FWIW (I think it's mentioned in the other thread I started), mine worked when I used one of the USB ports on the back of my Apple monitor (a hub there, presumably) instead of the ones on the front of my Mac Pro tower. I guess this wouldn't apply to the OP's Macbook Pro though. Maybe try it with a powered hub ? Try a shorter thicker cable ? Add a battery to the ESP32 so it has plenty of power ?

Hi, I have the same problem too. downloaded the recommended silicon labs drivers for usb to uart but still no luck. My Mac OS version is High Sierra 10.13.5.

Does anyone have the same problem too?

@Chris2060
Copy link

@bakzs Yeah I do have the exact same problem on my macbook pro... I have a Esp 32 Devkit V1 and installed the driver from espressif and the recomended one above, but I still cant see it in the arduino IDE. Im sad...
Someone any idea how to fix it?

@JohnGEyles
Copy link

Try the various USB ports, try a different cable, try a USB hub ...

@Chris2060
Copy link

@JohnGEyles Thanks for your advice!

I used the port at the back right with a different usb cable after a restart of the laptop. Now it works... ;-)

Installing the silabs Silicon Labs VCP Driver.pkg worked for me also. 👍
(on OS X 10.11.6)

Seems obvious that we need the drivers, but I thought I already had them after going thru the espressif/arduino-esp32 install steps.
e.g. My "System Report / Hardware / USB" showed
CP2102 USB to UART Bridge Controller driver

For others' future reference, you should see something like:
n8s-iMac:nleon$ ls -al /dev/tty.*
crw-rw-rw- 1 root wheel 18, 2 Jul 4 11:14 /dev/tty.SLAB_USBtoUART

Regardless, thanks for the pointer!

Having this issue too.
I downloaded all the drivers I found from different sources including the ones mentioned here. It flashed up as a recognised device briefly but then vanished again and I can't reproduce the result.
My board doesn't have a visible chip so I'm assuming its under the RF shield. Navigating to About this Mac → System Report → USB shows a "Composite Device" with Product ID "0xea60" by Silicon Labs so I hunted that down and its one of the CP2102s...

Still hunting.

EDIT: Running High Sierra 10.13.6

Anyone notice MAC drivers were updated yesterday - still no joy though

CP210x Macintosh OSX VCP Driver 5.0.5 - July 13, 2018

Known Issues and Limitations

This release includes the Macintosh OSX driver for 64 bit Intel 
Macintosh computers running MacOS X 10.11 or greater.
For MacOS X 10.9 and 10.10, see the folder called "Legacy MacVCP Driver".

@AcrimoniousMirth

Yeah, so I’ve tried identifying the device several other ways and it keeps showing up the same. My father’s old MacBook Pro also identifies it the same but when trying to view it in the Arduino IDE can’t find it, gets the same SOC and MALS.
Haven’t tried a Windoze machine because don’t have one handy!

@AcrimoniousMirth
Copy link

I’m actually wondering if this is more an issue with the Arduino IDE? Anyone had any luck with other IDEs?

@mattcony

Just caved and tried a win8.1 machine, up and running in 15min. I thought my new ESP32 board was bad, tried every usb cable in the house with no Joy on my MAC. Windows machine is fine, my MAC cannot even see the board in terminal so has to be driver related still.

Guys there are 2 drivers, the CP210x and CH340. I got those installed and
now all esp8266 and esp32 work with my 2017 mbp.

That’s interesting, don’t think I came across the CH340 driver being needed. I’ll install that soon and get back to you with my results too.

EDIT: Done and no change. I actually had the drivers installed before but reinstalled them.

EDIT#2: Actually there is a change. Didn’t show up any differently in any of my Mac’s native searches but finally appeared in the Arduino IDE as /dev/cu.SLAB_USBtoUART

EDIT#3: Has since vanished from the list again. I don’t know why, I didn’t unplug it or anything, I just went to double check and it was gone. This is somewhat infuriating.

@mattcony looks like it could be. Briefly wondered if emulation would work but doesn’t feel like it.

I am unable to see the SiLabs driver for the ESP32 Port on my Mac OS - High Sierra 10.13.3 for the ESP32.
After going over others comments above - I installed both the CP2102 and the CH340G ( since I play with the Arduino and ESP8266 ) but the port for the ESP32 on the Arduino IDE is not showing up after installing the driver.

I have multiple USB ports and so I plugged in the ESP8266 on the other USB Port - and I got the "cu.wchusbserial1410" and this is good. But the /dev/cu.SLAB_USBxxx for the ESP32 is not showing !
I was thinking maybe the USB Port caused it - so I tried both the USB Ports - no luck.

Note : I rebooted my Mac after installing the driver.
See below - the port for the ESP8266 shows up.

$ ls -l /dev/cu*
crw-rw-rw- 1 root wheel 21, 1 Jul 17 20:06 /dev/cu.Bluetooth-Incoming-Port
crw-rw-rw- 1 root wheel 21, 3 Jul 17 20:10 /dev/cu.wchusbserial1410

The ESP32 has the print DEVKIT1 on the back of the microcontroller

I had the same issue on a Macbook pro 2017.
I was using USB-C to USB-A adaptor, and USB-A to micro usb cable.
I added a basic usb 2.0 hub between the adaptor and the cable, and it's now detected.

Had the same issue with bei 2017 MBP. I bought a new USB A to Micro USB cable and now it works.

Had the same issue on a 2018 MBP, spent ages trying different cables and reinstalling drivers. On my Linux machine it just works but I have to use the MBP for work so to get it working:

Note, you may not need all those steps; I went overboard cause I am also trying to get a Linux partition working. Anyway, hope that helps someone. : )

Silabs drivers worked for me. Had to run the uninstaller.sh and then, in my case, install Legacy.

Now I see /dev/tty.SLAB_USBtoUART in Arduino IDE.

Cable for me, glad I read through this thread! Running a MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) and 11.4. My other cables work with other boards (Adafruit M0, MKR 1010) so I was shocked. Did the driver updates to no avail. Then used a 12" NIMASO USB-c to USB-C with a ARKTEK adapter and it worked, showing up as /dev/cu.usbserial-0001. Still wouldn't load the sketch--had to hold the Boot button to get the sketch to load. Hope it helps someone!

Hi do you have a link to buy this cable for me not work and I don't want to buy 1000 cables ;)

I'd recommend that you make sure that the cable you buy can transfer data. There are certain cables that can only charge.

I have an M1 Pro MBP 14" 2021 with Ventura 13.1. Had the same issues as described here. The following worked for me:

  1. Installed the Silicon Legacy Driver
  2. Used a proper MicroUSB to USB-A cable (had issues with a cheapo one)
  3. Connected using a USB hub (had issues with the Apple adapter)

Hi, I have Mac OS "Sonoma" 14.0 and it was a cable. Macbook pro 2019.

@bluemellophone

I was able to connect to a KeeYees ESP32 with esptool.py on a Apple M1 Max MacBook Pro running macOS Sonoma (14.1.1):

  1. Download the CP210x drivers here: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads
  2. Install the standard driver, no need to use the legacy driver
  3. Approve the System Extension in Settings > Privacy & Security
  4. Reboot
  5. Verify driver system extension is running with systemextensionsctl list and look for com.silabs.cp210x [activated enabled]
  6. Connect the ESP32 to a proper micro USB to USB-A cable
  7. Connect the USB-A cable into an Apple USB-C dongle (e.g., https://support.apple.com/en-us/HT207807)
  8. Verify ESP32 TTY with ls /dev/tty.* | grep UART
  9. Verify ESP32 is up and running with esptool.py read_mac

You should see something like this:

$ esptool.py read_mac
esptool.py v4.6.2

Another issue I figured out is that there is a USB-C style connection port but only with USB-A support. There is no resistor or id chip behind the port. With an adapter from USB-A to USB-C cable it works.

@bluemellophone

I had the same issue, but I used a different dongle / USB cable and showed right up.

@arivvid27
Copy link

I found that the issue is usually with the cable, or drivers not being installed. Once you install the drivers and the ESP32 is still in appearing the the serial ports, it is probably you are using a power only cable, instead of a data+power cable.

I had the same problem. Read this thread a year ago for the first time. Tried the driver. Didn't work.
Then I tried just a day ago different cables USB A to micro USB cables and the most "expensive" looking one of them worked... I'm more than happy :D
