- Fri Nov 13, 2020 1:21 pm #89427 You just saved my life! I thought it was a bad unit. thanks

I had this problem today to so i did a google search and found this site. I ended up fixing this on my own, so i thought maybe someone else need help, so i registered to this site, and now im gonna tell you how i solved it.

1. Press Start -> Type: Device Manager.
If u see a [!] mark next to CP210x USB to UART (COM..)
Even if u don't find that just install the following file.

2.https://www.silabs.com/products/develop ... cp-drivers
Select first one if u got windows10.

3.Install the file and your done.

Your welcome, for the one googling this and solving the problem.

If you are using Windows & CP2102 you have to go to the website and download the LATEST VERSION! It's the only way because device manager can't always detect the latest version:

I followed your very direction to download the latest version, which gave me a better result!
