Introduction

In a surprising move, Microsoft has officially blocked the Windows 11 24H2 update for computers that use USB scanners supporting the eSCL protocol. This protocol allows for driverless scanning over various connections like Ethernet, Wi-Fi, and USB, but its incompatibility with the latest update has left many users in a lurch.

Scope of the Issue

The disruption affects not only standalone scanners but also multi-function printers, fax machines, modems, and any other network devices equipped with eSCL protocol capabilities. Reports from frustrated users have inundated Microsoft’s community forums, Reddit, and other digital platforms for over a month now, compelling the tech giant to take action.

One user shared their plight on Reddit: “I’ve reached out to vendors for both my medical software and scanner. Ricoh, which now owns Fujitsu's scanner branch, has no fix yet, but they’re working on it.” This comment, posted on October 31st, highlights the ongoing struggle faced by users who rely on these devices for their daily operations. Meanwhile, another user voiced frustration, stating, “This issue has struck five of our computers after the upgrade. Even with new drivers and firmware attempts on HP, we’re still facing issues.”

Root Cause of the Chaos: USB Mode Switch Failures

Microsoft has acknowledged that the problem stems from the failure of devices to switch from eSCL to USB mode. This switch is critical for properly matching scanner drivers with connected devices. In an official statement, Microsoft elaborated, “After installing Windows 11, version 24H2, users might find that their USB-connected devices employing the eSCL scan protocol are not discoverable, leading to incomplete device discovery.”

Microsoft's Response

To protect users, Microsoft has implemented a compatibility hold, preventing the Windows 11 24H2 update from being offered to systems utilizing USB-connected eSCL scanners. Those affected are urged to refrain from using the Media Creation Tool or the Windows 11 Installation Assistant for manual updates until a solution is available.

Conclusion

As software issues like these can significantly disrupt both personal and professional workflows, affected users must stay informed on updates from Microsoft and their scanner manufacturers. This situation underlines the importance of ensuring compatibility before major updates.
