Microsoft has invented an upgrade block for the Windows 11 24H2 update because it breaks USB network modems, printers, and scanners. The problems may be related to eSCL, as Microsoft has confirmed that the protocol does not work in Windows 11 24H2.
Earlier in June 2024, Microsoft has announced several changes in printer support, making emphasis on Mopria standard as the less problematic one for the newest OS. Still everything is not going smooth, and the feature update has been blocked.
The issue, as Microsoft explains, is that devices do not switch USB mode from eSCL when needed, which essentially causes a conflict. After installing Windows 11 version 24H2, you may have trouble detecting USB-connected devices that support the eSCL (eScanner Communication Language) scanning protocol. This issue primarily affects multifunction devices connected via USB or standalone scanners that support scanning features and the eSCL protocol.
eSCL is a driverless scanning protocol designed for network scanners. It enables driverless scanning over network (Ethernet, Wi-Fi) and USB connections.
The company has applied a compatibility block on devices that support the eSCL scanning protocol. IT administrators using Windows Update for Business reports can check for the issue using security ID 54762729.
Issues with Ubisoft games
Earlier, Microsoft announced that it was pausing the rollout of the Windows 11 24H2 update for PCs with Ubisoft games installed. Changes to the operating system lead to crashes, freezes, or sound problems. The games may stop responding when launching, loading, or during gameplay. In some cases, users may see a black screen.
The list of affected titles include Assassin's Creed Valhalla, Assassin's Creed Odyssey, Assassin's Creed Origins, Star Wars Outlaws and Avatar: Frontiers of Pandora. However, gamers also reported similar problems with parts of the Far Cry series, as well as with Activision's Call of Duty. The company is working with Microsoft on a permanent fix.
