Error Code 31 with 8.2M0 on USB Monitor

[AlbanRampon]

Microsoft has helped me by approving the changes straight away.
The driver won't be distributed to you from Windows Update anymore.

We do still need to understand what took place though: if we don't get to the root cause, this is likely to happen again and I certainly don't want that!!!

May I start a support ticket with you to get to the bottom of this?
Kind regards,

Yes, definitely

The issue is a particular one as i have this model of monitor on 3 other different computers and, for now, there is no problem with them.

I uninstalled display link software, run the cleaning tool and installed v. 8.0.M3.

Monitors are working now.

Attached the logs.

Good afternoon,

Something which looks like a common theme here (common on less than 5 reports is not really that common though) is you are using a Windows 10 N version.

Would you mind trying to install 8.2 M0 and also install the Windows 10 Media Feature Pack? It is possible that a dependency on a DLL not present in your special version of Windows could be the reason why our driver doesn't start. I would like to check this hypothesis with you to see if we're looking at the right area to find a solution.

Kind regards,
Alban

Good afternoon,

We have been able to confirm the root cause last night, after reproducing locally.

The issue was coming from an unmet dependency.
The dependency is new in 8.2 and was introduced to support something new.

Windows "N" is a version of Windows without some files, not only without some applications.
Users of Windows 10 N can use 8.2 M0 and 8.2 M1 by installing the Windows Media Feature Pack.

Engineering is currently reviewing the dependency and alternative methods of trying to use it.

Kind regards,
Alban

I installed Windows Media Feature Pack (not the x64 one because it said it was not compatible with my os) and then driver 8.2 M1 and monitors do not work. Attached the logs.

Strange, your system reports to be x64:
OS: Microsoft Windows 10 Pro N (x64-based PC), No Service Pack, English

Can you search the computer for "mfplat.dll". The install of the media pack might have not been successful?

I'm expecting a development build of 8.2 M2 early next week to be able to validate the change in our driver with you.

Kind regards,

Good afternoon,

I have privately shared an 8.2 M2 Development Build with you.
This will confirm we fixed what you have been seeing as opposed to what we think you had!
Simply reply to the email if/when you try, preferably within the next week for 8.2 M2, to share your feedback.

Kind regards,
Alban
