Today i get it my First Nano ESP32.
I try some sketch witch working with no problem

After pause playing i to upload sketch to my New Nano ESP 32 i get the folloing message :
No DFU capable USB device available
Failed uploading: uploading error: exit status 74.

Its my first one Arduino Nano ESP32 to try and is dissapointing me .

I try from Arduino IDE Tool , Get board info and Get:
Board : BN: ESP32 Family Device
VID: 0x303A
PID: 0x1001
SN: (null)

Also in the lower Right Corner on the Arduino IDE i see the IDE recognise A Arduino Nano ESP32 is connected at COM7

I Change Usb cable but not changing nothing .
Also change Usb port on my laptop but nothing .

Hi @vaggoscc. Please try this experiment and then report back with the results:

  1. Connect the Nano ESP32 board to your computer with the USB cable.
  2. Press and release the button on the board marked "RST".
  3. Wait for the RGB LED near the "RST" button to turn on.
    ⓘ It does this almost immediately, but you do need to wait for it.
  4. While the RGB LED is still on (it only stays on for a second so you need to be somewhat quick), press and release the "RST" button again.
    The green LED of the RGB LED should now start pulsing. If not, repeat the process in case you didn't get the timing quite right.

Now please reply here on the forum thread to tell us whether the LED went into the pulsing state described above when you performed the instructions.
