Hello, I was using an arduino nano to drive a stepper motor and display something to the serial monitor every 0.1 seconds. I then tried to upload another code to it but it didn't work. I unplugged the board but as soon as connected it back, the TX led started flashing and after a few seconds windows gave me an error that the USB device is not recognized (I plugged the motor back in and the board is ok,because it started ti drive it again). I tried pressing the restart button but it didn't work, the board is stuck in trying to push serial data to windows. I had a similar problem with a LPC1768 where I unplugged the board while it was accessing a file and had to go through their guide to recover the board. what is the recovery process with an arduino nano?
(I can't upload a blank file because it doesn't reven recognize the board)
here's a picture of the windows error btw:
Never connect stepper motor to your Arduino.
If I had to bet money, your Nano is bricked.
Read the spec on much current it can source on 5V. It isn't enough for a stepper motor.

Did you even read the question? I was using the board to generate square waves to drive a stepper driver and an external 60 watt supply but that's besides the point, the main problem is the serial line which means I can't reprogram the board, the code that's already on it works perfectly fine

That's not what you wrote.
I will quote your original post, so that you can't change it and make me look like a fool.

Dude are a 5 year old or what? I don't need to make anyone look like a fool. If you want to help at least understand the question ... I'm just trying to get my issue fixed, not to prove anyone wrong.
I said there's something wrong with the USB serial port not the board itself

anyways, I plugged it back and somehow the code didn't start automatically again, so I managed to flash the memory with an empty code and it's fixed now. I don't know what was wrong with it to begin with, but caps should have drained and done smething ... idk

You did not describe what actions you took that caused your problem.
You have no freaking clue!
If you expect any help in the future and from the looks of it you will, you had better learn how to do that correctly.
