Windows 10: USB to Serial connection

Does anyone know a fix for USB to serial? Windows 11 doesn't seem to support that, and I've tried downloading drivers from Prolific, but it says it's not Windows 11 compatible. There must be a fix somewhere. Need to connect a 9 pin, 9600 BAUD serial to USB device to a windows 11 OS and apparently Windows 11 doesn't support that

Serial to usb driver

Hi, malick diouf1

Welcome to the MicroSoft Community.



Yes, you may need to install a serial to USB driver on your computer in order for it to recognize the device. Here are some steps that may help:

• Make sure that the serial to USB cable is connected properly between the modbus slave device and your computer.
  
• Go to the website of the manufacturer of the cable and look for the driver download page. Download the driver that corresponds to your operating system.
  
• Once the driver is downloaded, run the installer and follow the on-screen instructions.
  
• After the installation is complete, restart your computer.
  
• Open Device Manager by searching for it in the Start Menu.
  
• Look for the "Ports (COM & LPT)" section and expand it.
  
• Your serial to USB device should be listed here with a COM port number assigned to it.
  

If you do not see the device listed after installing the driver, try unplugging and plugging the cable back in or using a different USB port on your computer. If the problem persists, contact the manufacturer of the cable for further assistance.



If there is anything not clear or I can't understand your problem, please do not hesitate to let me know.

Can't get USB to serial converter to work

Hi, here to work with you on this issue.

If Windows is indicating that the USB to serial converter won't start and suggests reloading the driver, but you've already attempted that and it still doesn't work, there are a few troubleshooting steps you can try:



1. Unplug and reconnect the USB to serial converter: Disconnect the converter from your computer's USB port and wait for a few seconds. Then plug it back in, ensuring it is securely connected. Sometimes, a simple reconnection can resolve connection issues.



2. Try a different USB port: Connect the USB to serial converter to a different USB port on your computer. It's possible that the current port you're using is experiencing problems, and trying a different one might help.



3. Restart your computer: Sometimes, a system restart can fix driver-related issues. Restart your computer and see if the USB to serial converter starts working after the reboot.



4. Update the driver manually: Even if Windows claims the correct driver is installed, there's a possibility that it may be outdated or corrupted. You can try manually updating the driver by following these steps:



a. Go to the Device Manager by right-clicking on the Start button and selecting "Device Manager" from the menu.



b. In the Device Manager window, locate the USB to serial converter. It might be listed under "Ports (COM & LPT)" or "Universal Serial Bus controllers."



c. Right-click on the USB to serial converter and select "Update driver" from the context menu.



d. Choose the option to manually search for the driver. You can either provide the specific driver file if you have it or let Windows search online for the latest driver version.



e. If Windows finds an updated driver, follow the on-screen instructions to install it. Once the installation is complete, restart your computer and check if the converter starts working.



5. Contact the manufacturer's support: If none of the above steps resolve the issue, it's recommended to reach out to the manufacturer's support for further assistance. They may provide specific troubleshooting steps or advice tailored to your USB to serial converter model.



Remember to provide as much information as possible when contacting support, such as the make and model of the USB to serial converter and the version of Windows you're using.

I hope this is helpful. If you require any additional assistance, don't hesitate to respond to this.

Regards,

 

Windows 10 serial on OEM


So I'll summarize steps made...

1. Saved serial number (taken with Belarc Advisory) from preinstalled (half chinese language) Windows 8.1 (don't know exactly the version, suspect Windows 8.1 with bing) on tablet
2. Formatted tablet
3. Tried to make a clean Windows 10 (HOME, HOME N and also PRO, everytime with the same result) install with ISO taken with MediaCreationTool, during install (and also after completing installation) it says that the saved serial is not valid
4. Tried to reinstall Windows 8.1 (ISO taken with MediaCreationTool again) HOME, it says that the serial is not valid

So i suspect that the saved serial, is from a WINDOWS 8.1 WITH BING OEM version and this kind of ISO is not accessible/downloadable anywhere (at least I can't find it, any suggestion?)

Still not tried SHOWKEY with that serial, I am in office now, and the serial is saved on a usb pen at home, will try this evening.

So I'm stucked but if everything is like I suspect, it's incredible. If I have a tablet/notebook/netbook with Windows 8 preinstalled, it seems that I can update to Windows 10 without problems, but if I want to make a clean Windows 10 install that serial is not valid...
