General issue report

Hello everyone, I submit this feature to add a possibility to connect the ESP32 to the MCU through USB cable. In my case, I have 3 hubs, each hub has an Stm32 USB device Vendor Specific (see below) that i want to connect to an ESP32 through USB and next send it through wifi.

Ideally, i'm looking for this :

In theory you could use USB/IP protocol, but this may be not so easy to do it. All depends on stm32, and i still dont understand why you want/need esp32 connected to PC. It is enough that PC is connected to wifi or with ethernet cable.

@chegewara thanks for your reply. I think you said me before that your PoC for USB IP is not working well. the reason is : I want to avoid for people to connect through wifi, they will just connect the ESP32's and it will work directly like bluetooth mouse for example.
