CP210x USB to UART Bridge VCP Drivers NOT working on MacBook Pro
I've been trying to get these devices working on a 2017 MBP with USB-C for a week now. One ESP32 dev board has CP2102 and works reliably. I have small CP2102 USB to Serial breakouts from several different sources, and another ESP32 board from another manufacturer that do not work. They do not show in the system report, or anywhere. VirtualBox does not see them. I see no error messages in the system logs. The devices that have a status LED only flash, and do not stay solid like they normally would. They all work on my older, 2012 MacBook Pro. I tried the legacy driver and it did not work either. Tried uninstalling each time, installing twice, rebooting, installing again, etc... No luck until today.
Finally, I found that if I run them through a powered USB 2.0 hub, they all work perfectly. They all consistently show up as /dev/cu.SLAB_USBtoUART
I hope this helps someone!
