Wireless USB extension trough ESP32

Other Hardware Product Design

I need to upload code from my desktop to esp I have mounted in my garage.
I don't want to remove it and I don't have laptop so I came up with idea to cut USB extencion cable in half conect each side to ESP32 and via cloud send the USB data. Like in the picture.

I tried setting up a codes for both ESPs

For the female side: (Only what i wrote, the conection to cloud is not here)

void setup() {
  pinMode(d_g, INPUT);
  pinMode(d_w, OUTPUT);
}

void loop() {
  d_green = digitalRead(d_g); 
  digitalWrite(d_w, d_white);
}

And for the male side:

void setup() {
  pinMode(d_g, OUTPUT);
  pinMode(d_w, INPUT);
}

void loop() {
  digitalWrite(d_g, d_green); 
  d_white = digitalRead(d_w);
}

When i plug usb thumb drive into the port the PC registrated it but that is it. Sometimes it just show an error mesage saying that the thing i conected canot be used.

I'm stuck here. I wasn't able to find anything helpfull online so Im asking here for some advice.

USB works at 5 Volts and you will need analog reads as it is using differential voltages to communicate. ESP32-USB-Soft-Host/examples/ESP32-S3-USB_Test/ESP32-S3-USB_Test.ino at main · tobozo/ESP32-USB-Soft-Host · GitHub can be a good starting point. The USB communication timings are critical. I would love to do the same as what you are trying but with printers and Im sure there are others who are interested.
