A Arduino UNO Q can not be detected by windows 10 after flash a new Linux OS

Official Hardware UNO Family UNO Q

Hello,

My Arduino UNO Q previously worked perfectly in SBC and PC host modes, but after flashing a new Linux system, Windows 10 can not recognize it. I've tried different USB ports and replaced some USB cables. I've restarted my computer and also tried using it on another Windows 11 PC. I can't find it in Device Manager. I've also tried using the "/dev/tty*" command in the Linux and Mac terminals, but no new device prompt appears.

Can anyone help me? Thank you in advance.

Just noticed that five days have gone by and no one has responded. I am wondering if you have been able to resolve the issue yourself?
I think the following video might help as it shows someone going through the process and what worked for him. He does it twice in the video. Once with a mac and once with a windows machine. I set the link to start where he is showing the procedure on a windows machine. I do not know if that will help but perhaps you can see if you did all of these steps.

Hi @qazzaq123321. If you haven't already, please try repeating the operating system image flashing procedure again:

https://docs.arduino.cc/tutorials/uno-q/update-image/

It might be that a problem occurred during the previous flashing operation and that left the board in an unusable state.

Please add a reply here to let us know what happened when you did that. Was the flashing operation successful the second time? Does the problem of the board not being recognized still occur after doing that?

Hi danpeirce,

I re-flashed the Linux OS after watching the video you provided. The USB-C port is still not recognized, but the Wi-Fi mode is working properly now.

Thank you for your concern.

Hello ptillisch,

Thank you for your concern.

I have re-flashed the Linux OS. Currently, I can only use the Arduino App Lab by connecting the development board to my computer via Wi-Fi.

Hello danpeirce and ptillisch,

I use this board on another Windows PC with a USB-C/A ports. It works fine with a USB-C to USB-C cable, but not with a USB-A to USB-C cable.

Thank you for your help.

Great work on troubleshooting the problem!

This finding might indicate that there is a problem with the USB cable. The cable might be defective, damaged, or only intended for use as a power supply for applications like charging a phone (no data lines). If you have another USB cable on hand, try switching the cable.
