So far, I have hooked up a MEGA and have it working great. Then I bought these:

https://www.amazon.com/gp/product/B07QCP2451/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

I am unable to install any firmware due to "Failed to connect to ESP32: Timed out waiting for packet header". I have tried each of the two ESP32 units and neither work. They're hooked up to my computer via USB and I'm trying to install over serial. 
Are these not what I think they are? Or any thoughts on why they are not communicating/receiving firmware? 

Additional details (I'm new to this, I don't know what is relevant): I was able to add a driver, and the driver is "Silicon Labs CP210x USB to UART Bridge"

Thanks!

Try pushing the boot button (right side when USB port is pointed toward you). It will then begin to accept the download.
