The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver. To use the CP2102 on a computer running Mac OS X, you should download and install the CP210x USB to UART Bridge VCP Drivers from Silicon Labs for Mac OS X. Additionally, we have older drivers that other customers have used successfully on both PowerPC- and Intel-based Macs running OS X version 10.3. I have the ESP32 board with Silicon Labs CP2102 controller. When I connect it to my MacBook, I can get the details about this device using the command system_profiler SPUSBDataType, but it is not l.

I have the ESP32 board with Silicon Labs CP2102 controller. When I connect it to my MacBook, I can get the details about this device using the command system_profiler SPUSBDataType, but it is not listed in /dev as a virtual serial port - so I can't communicate with it.

I'm using the official driver downloaded from https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.

Any ideas how to make it visible in /dev? I have also Windows installed on the same computer where it works fine, so the HW and the USB cable are OK.

I found that macOS High Sierra has blocked all unsigned / unmanaged kernel extensions and the SiLabs kernel extension guide doesn’t have information on how to manually enable the required extensions.

Here are steps to allow this extension specifically:

Go to 'System Preferences' -> 'Security & Privacy'
In the bottom of the window, you will see a message 'System software from developer 'SiLabs' was blocked from loading.'
Click on 'Allow' button
Restart your Mac

Now my device is listed as /dev/cu.SLAB_USBtoUART and everything work as expected.

Check to see if your board is recognised as described in this link, and if yes and still no communications, you may need to install libusb with homebrew or similar. A good tool to play with before anything else is CoolTerm (easy to find..).
