So - up until Mojave the mac-usb-serial drivers were pretty solid - and the serial detect app is also a fast way to find out what chipset a device is using - but - for CH341 and CP2102 at least I don't seem to need to install extra drivers any more.
The CP2102 includes a USB 2.0 full-speed function controller, USB transceiver. I tested tonight - and all my devices work on catalina out of the box - no custom driver needed. Quote from the CP2102 chip datasheet, there mention that the CP2102 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. However - while looking into if they were ready for catalina I stumbled across a post (to which I've sadly lost the link) stating that apple had added some support. ESP32/ESPS32S ESP32-Bit CP2102 Widora-AIR V4.0 ESP8266 Bluetooth Wifi. My usual devices are the Wemos D1 mini (CH341), the Wemos D1 mini pro (CP2102) and the Lolin D32 (CH341) - the first two are ESP8266, the last an ESP32.Īfter testing a lot of free drivers - I downloaded the serial detect app from - and then when that detected the devices - I actually bought the drivers and they have worked well. Planted Seat Bracket - 1996 - 2000 Volvo V70 Wagon - Driver Side (Left Side). Up until recently - working with ESP8266 and ESP32 devices on Mac OSX required obtaining USB to serial drivers so that the correct port under /dev/ would work when the device was connected.
