PC does not recognise Arduino UNO R4 WiFi

[l-c]

Hi
I have a copy of the Arduino UNO R4 which I have not yet been able to use as the board is not recognised by the PC (Windows 11). If I try to connect it I get a notification and if I open it the following message comes up:

(sorry, the PC is in Italian: the text in the image is a translation)
If anyone knows what this problem might be due to I would really appreciate any advice/solution.

Thank you very much, have a nice day everyone!

Hi @l-c. Make sure the USB cable is fully inserted into the USB socket on the UNO R4 WiFi board and your computer.

If that doesn't help, try using a different USB cable. This error might be caused by using a low quality, damaged, or defective cable.

Also, make sure that it's not just a charging cable.

Someone else here also having trouble with Win-11 not recognising Arduinos:

Ardruino Nano and Pro Micro CH340 Not recognized by Win 11

Hello, Newer here very frustrated as Ive purchased a couple of Nano,s and a Sparkfun Micro, and both boards are totally unrecognized by Win 11 with USB 3.0 ports on my laptop. Ive tried forcing legacy hardware, restarting in driver signing off mode, of course downloading the driver directly from the wch vendor. No Luck it never recognizes the board at all and ports remain greyed out. When I try to install the drivers it never recognizes a device and wont allow me to select the driver files manu…

In your case, it does seem to the Windows itself that's not seeing the device.

Arduino UNO R4 non viene riconosciuto dal PC

Buongiorno Possiedo una copia di Arduino UNO R4 che non sono ancora riuscito ad utilizzare dato che la scheda non viene riconosciuta dal PC (Windows 11). Se provo a collegarla mi esce una notifica e se la apro esce il messaggio seguente: [image] Se qualcuno sa a cosa può essere dovuto questo problema gradisco molto qualsiasi consiglio/soluzione. Grazie mille, buona giornata a tutti!

Le PC ne reconnait pas Arduino UNO R4

Hi J-M-L ...
... in the Italian section, since there was no answer to his question, I suggested to the OP to write in the section dedicated to the board (but not in the French section ).

So ... he is only half guilty

@gpb01

he is only half guilty

ok for half.

If you tried all of those tips and connection issues persist, make sure you use the latest Version of the Arduino IDE.

[awneil]

OP says it's not even being seen by Windows - so the IDE is irrelevant here.

Hi, same problem here
Can't be the IDE (windows can't recognize the board) and it can't be the cable (if the calbe is charging only, the board is powered correctly but from the pc you do not even see the windows error message)

EDIT: I tried with a fourth USB-C cable, asking my neighbor for it, and this one works

[gions69]

I have the same problem too, can you tell me the specifications of the cable that solves the problem?

Thank you

Giovanni

[bertaz31]

I bought a USB-C which is for power and data transfer. Just make sure you can trasfer files with the cable. If it's chargin only, it won't work

[shadowme]

I’ve solved it by removing the board from the board manager and re-installing it. I had the same problem, but it wasn't the cable. Likewise, I hope this can help.

[awneil]

That wouldn't help if it's the PC itself that isn't seeing the device?

You really provided me with the solution. I used the USB-C cable from my phone and it resolve the issue of not recognizing my Uno R4 wifi when using a USB-C cable provide with my headphones.

Thanks

Hello everyone, I have difficulty with my Arduino UNO R4. It is not recognized with Windows 8.1 and Windows 11. I have tested with an USB 3 cable (blue). I think it is a driver issue but none drivers I downloaded work. Can someone help me ?
