Hi,
   90% of the time its the cable, you need a micro b cable that supply power as well, not all micro b cables does this
Ideal for charging Android phones and tablets or
connecting PC peripherals such as hard drives, printers, and more

Hope it helps
 
 
 
 

Thanks for the information. My need is rather more basic. I am installing in a Linux (Ubuntu) machine and I am not yet familiar with using the system. The app notes from Silicon Labs appear to deal only with Windows applications. I have read how to use ‘make’ to build an application. In which directory should I attempt to install.

Hello John, do you already have Arduino IDE installed? If so, open Arduino IDE and connect your ESP32 to your computer:

• Go to the menu: Tools > Port
• Which port do you see there? What’s the name?
• Then, remove the board from your computer. 
• Go again to the menu: Tools > Port. Is it empty now?

If you see a Port while your ESP is connected to your computer, you don’t need to install any drivers. Let me know your results.

Hi Rui,
IDE is installed and running. There is no port shown with or without ESP32 board. From your Ebook I presume I need to install the Silicon Labs CP210x driver. I have obtained the code but I am not sure how or where to install it. This is where I need some help.

Hi again,
 
 
 
 
 
 
 
 
 
 
Hi again,
Searching with ‘modinfo cp210x’ it seems that cp210x is already installed. How do I link it to Arduino IDE.
 
 
 

Hello again,
I have re-installed arduino ide using ‘ubuntu-make’ and it is now fully working. This enquiry can now close. Thanks to all for your help.
John.

I apologize for the trouble John and I’m glad you made it work. Thanks for posting the solution that made it work. I’ll mark the thread as “closed”. Regards,
Rui
