Problems with COM PORT on Windows with ESP-WROVER-KIT

[robocode]

Dear All

I just installed the ESP-WROVER-KIT and all software using directive from https://esp-idf.readthedocs.io/en/lates ... index.html on three Machine (2 win10 and 1 win7)

In all situation it's not possible to flash because COM communication.

I tried in all of them, just only starting computer and plugging KIT to test the correct working via Putty (as explained in https://esp-idf.readthedocs.io/en/lates ... ction.html).
By the way in all computer look like NOT possible to OPEN the port.

I see ports, (example COM3/COM4 ), and I set correct parameters.

Only one time I was able to see something (dbg,dbg,...) and all other times Putty wasn't able to open port.

Look like a FDTI driver problem or something else.
Has anyone any idea to help us ?

Hi robocode,

This does sound like a driver issue. Exactly what happens in Putty when you try to open the port? If you check Device Manager, does the port show up there with no warnings or errors?

Hi yes,
l think too it should be a driver issue.

In Win10 I see no problem in device panel (all perfectly shown).
Whe I try to open using putty I hear a notification sound, but show nothing in terminal

Sometimes (I really don't know when) I was able to open terminal and I saw a repeating message (dbg,dbg,dbg...)

Thanks for your answer
