Introduction

Microsoft has recently revealed that its upcoming Windows 11 24H2 update encounters significant issues with USB-connected devices that rely on the Scanner Communication Language (eSCL) protocol. As a precaution, the tech giant has implemented a compatibility hold on these devices, meaning they will not receive the upgrade until further notice.

Impact on Devices

The compatibility hold specifically affects USB-connected multifunction printers and standalone scanners that utilize eSCL for scanning functionality. Microsoft elaborated on the matter, stating, “You might observe that your device does not discover the USB-connected peripheral, and the device discovery does not complete.” This problem stems from the device’s failure to switch from eSCL mode to a more compatible USB mode, preventing the necessary scanner drivers from being recognized correctly.

Scope of the Issue

But it’s not just about scanners; this hold affects any hardware connected via the eSCL protocol, including printers and even some fax machines. While the prevalence of fax machines in modern workplaces may be dwindling, Microsoft’s Windows Fax and Scan application remains a nostalgic nod to older operating systems like Vista, still surprisingly relevant in today’s digital landscape.

ARM Users

Interestingly, users running an ARM version of Windows 10 or 11 might find themselves immune to these issues—although reports suggest that traditional fax machines far outnumber ARM Windows devices.

Understanding eSCL Protocol

The eSCL protocol, part of the Mopria eSCL specification, allows for driverless scanning over network connections, whether through Ethernet, Wi-Fi, or USB. This innovation simplifies the scanning process but comes with its own set of challenges in compatibility with Windows 11 24H2.

User Guidance

While the updates through Windows Update will be on hold, users in dire need of the latest features can opt to manually install Windows 11 24H2, albeit at their own risk. Microsoft has advised affected users to wait for a resolution before proceeding with upgrades.

Conclusion

Stay tuned as this situation develops—it may not just affect your scanner, but it could also impact other critical office hardware!
