Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to win 11 24H2.

Also, I found a Microsoft known issue related to scanner:

After installing Windows 11, version 24H2, you might experience issues discovering USB connected devices that support the eSCL (eScanner Communication Language) scan protocol. You might observe that your device does not discover the USB connected peripheral and the device discovery does not complete. This issue primarily affects USB-connected multifunction devices or standalone scanners that support scan functionality and the eSCL protocol.
Resolution: This issue was resolved by Windows updates released December 10, 2024 (KB5048667), and later. We recommend you install the latest security update for your device as it contains important improvements and issue resolutions, including this one.
Have a nice day.
Best Regards,
Molly
