ESP32 CP210x USB to UART does not come up in device manager when plugged in

Postby stabathane » Sun Aug 16, 2020 12:51 am

When I plug in the esp32 to my laptop it says "Unknown USB Device (Device Descriptor Request Failed)" and because of this the chip cp210x driver won't work. My computer is saying it cannot connect to the device. I tried forcing a manual update in device manager but it said the best update was installed which isn't true because when clicking on driver details it said no driver. I uninstalled all usb serial communication drivers and restarted my computer to see if that worked and it didn't. I know the esp32 works because I plugged it into another computer and it showed up in device manager fine and took the driver. Why won't my computer detect the esp32?

That does not sound like a driver problem, more like a hardware issue. Can you try a different cable? What happens if you plug the board into a different computer?
