ESP32-S3: Wi-Fi and USB (CDC ACM Host) Incompatibility – USB CDC-Host not work with WIFI (IDFGH-14286)

[antunesls]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.4.0

Operating System used.

Windows

How did you build your project?

VS Code IDE

If you are using Windows, please specify command line type.

PowerShell

What is the expected behavior?

Connect to wifi as station (client) and comunicate as a USB host , using serial connection.

What is the actual behavior?

When start the wifi connection the USB stops to work, not even detect new devices.
