Dear Microsoft Support Team,
I am writing to seek assistance regarding a critical issue we are experiencing with serial port access and USB to serial access under Windows 11.
Since upgrading to Windows 11, we have encountered persistent problems that significantly affect our work. Specifically, Working with Serial Port and USB Serial Adapter
These issues are disrupting critical operations that rely on stable serial communication. We have already taken the following steps in an attempt to resolve the problem:
- Ensured all device drivers are up to date.
- Tested the hardware on alternative machines running Windows 10, where they function correctly.
- Checked for any Windows updates or patches that might address known issues with serial ports.
I would greatly appreciate any guidance or support you can provide to resolve these issues. This matter is urgent, as the inability to use serial ports correctly impacts my ability to perform essential tasks. I cannot overstate the importance of your help in this situation.
Please let me know if there are any known issues with serial port access in Windows 11 or if there are specific troubleshooting steps I can follow to rectify the situation. Your prompt response will be highly appreciated.
Thank you for your attention and assistance. Your help in resolving this issue is greatly appreciated.
Best regards,
Amit Kumar Agrawal
