Microsoft is facing challenges with the Windows 11 24H2 update, including bugs that disrupt functionality. A significant issue involves a glitch in changing time zones without administrative privileges, acknowledged by Microsoft within the Settings app. Users have reported USB connectivity problems, leading Microsoft to block the update on devices using the eSCL protocol. Compatibility issues have affected multi-function printers, scanners, modems, and other network-connected devices relying on eSCL, as the operating system struggles to transition from eSCL to USB mode. Microsoft confirmed that users may experience difficulties discovering USB connected devices that support the eSCL scan protocol after installing the update.

Microsoft has acknowledged a compatibility issue with Windows 11 24H2 affecting USB-connected devices using the Scanner Communication Language (eSCL) protocol. A compatibility hold has been implemented, preventing hardware that supports eSCL from upgrading to Windows 11 24H2. This issue primarily impacts USB-connected multifunction devices and standalone scanners. Users may experience failure in device discovery for USB-connected peripherals after installing Windows 11 24H2. The problem arises from the device's inability to switch from eSCL mode to USB mode, which is necessary for proper driver matching. This limitation also affects other devices using the eSCL protocol, such as printers and modems. The eSCL protocol allows driverless scanning over network and USB connections. The compatibility hold affects upgrades via Windows Update, but users can manually install the update if desired. Microsoft advises affected users to wait for a resolution before upgrading.
