How to use CP2012 on El Capitan

Hi,

This might be an advanced topic, but I'd like to use my Wio Node with the Arduino core for ESP8266 WiFi chip. I installed the latest driver (from http://www.silabs.com/products/mcu/Page ... ivers.aspx) for CP201x on MacOS El Capitan, but my device is not recognized.

It seems that there is an issue on El Capitan.

I tied with a USB 2.0 hub as suggested, but got no success.

If you know a way to use a Wio Node on MacOS El Capitan, please share your tips. ;)

Best,
Shigeru

Sounds like you were on the right path. The exact part number in the wio schematic is a CP2102.

Seems like there are some solutions in that search, but I cannot confirm. Sorry I couldn't be more helpful.

Your device is Wio Node (http://www.seeedstudio.com/depot/Wio-Node-p-2637.html)?
This Wio Node have not USB-to-UART chip. The USB connector just power.

Wio Node does not include UART to USB chip. It just upgrade by OTA.
