MY PC DOES NOT RECOGNIZE MY ARDUINO UNO

Hi,
I’ve bought an arduino uno R3 (non-official) and it’s works fine for one month, but now when I plug-it on my pc, it don’t recognize my arduino :frowning:
I’ve already tryed to update driver and reset my arduino .
But it always comes to the same error:
Here is the error log in the Arduino IDE when I put the Blink basic code:
avrdude: ser_open(): can’t open device “\.\COM3”: Le fichier spécifié est introuvable.
Erreur lors de la gravure de la séquence d’initialisation.
Can you help me ?
Cheers

Can you help me ?

Is the Arduino still connected to COM3? Or, is it now connected to a different COM port?

i tryed with all of my pc ports and it doesn't works :'( I updated USB driver with the file ch340ser.exe and nothing changed. And when i update driver manually by devices manager (i select the arduino UNO.inf file) my pc say error during the driver updating :'( In my ARDUINO IDE I can't select a port (the line is in grey). On my arduino uno R3 ATMEGA328P-PU the "L" led and "on" led" are turned on .

In my ARDUINO IDE I can't select a port (the line is in grey).

Then it is pointless to try to upload anything.

my pc say error during the driver updating

I'm almost certain it said more than that.

Hey LoadzFire,

You should try this thread https://forum.arduino.cc/index.php?topic=302362.0

Let me know if it works.

Thank for answer me,
When i plug my Arduino I dont see it on COM category in the device manager, so i can’t unistall driver :’(.
I try to plug my Arduino in the other usb port of my pc, same error :frowning:
Have you go an idea ?

Your IDE version?

I download and install the very latest version (1.8.0) and i've download it one the official arduino website

Hello,

Did you try your Arduino on an another PC?

yes but i think i find the problem, I use my arduino with unojoy to make this projecthttps://www.youtube.com/watch?v=93oCS9nF_y0, And now when i want to turn my arduino as an arduino (because now it is in joystick mode) the cmd say :

The firmware was NOT loaded...

Did you install the Atmel FLIP program? - http://www.atmel.com/tools/FLIP.aspx -
Is the Arduino plugged in?
Is is it in 'Arduino UNO DFU' mode?
Press any key to exit..
