Device issue after upgrade to MacOS 10.15.4

[jhillster]

Jakub,
Updating the D6000 firmware with a Windows system worked.
I updated the D6000 with Windows.
Windows system rebooted. Logged back in and confirmed the update.
Disconnected the D6000 from Windows and connected it to my Macbook.
Started the existing DisplayLinkManager.app that was already installed.
It prompted me to the instructions online.
I followed the instructions to open Security & Privacy
Click on Privacy tab
Selected Screen Recording
Gave DisplayLink Manager.app access
Restarted the DisplayLink Manager.app
Bingo - my third monitor is working now with the printer.

Thank you for direction on this and happy to test various revisions for you, Jason Hill

DisplayLink software only enables products with DisplayLink technology. Based on your log files and devices used by you I may see that they are not using DL powered devices. We advise you to check with your manufacturer as we do not believe this device features DisplayLink technology. We are looking into this issue and how to overcome it. In the meantime, having third party devices impacted seems to suggest this issue does not come from DisplayLink driver.

Best regards,

Sure? I think it is. I see that the DisplayLink isn't shown under USB Devices anymore since 10.15.4..... Before it worked great with the latest driver...... IcyBox / Raidsonic refers me to Displaylink.....

Hello,

Thank you for your patience.

Yes, based on the logs and the device specification I am sure that this device is not using DisplayLink chipset. It is clearly visible by checking vendor ID and that the specification mentions Alt-mode as a powering technology.

Best regards,
Jakub

My config is Macbook Air 2012 connected to Asus VE278Q using a Mini DisplayPort to HDMI cable. I was on Mojave and everything was fine, now I upgraded to Catalina 10.15.4 and the external monitor stopped working.

Hi Jakub, is there any update for my case above?

A firmware update of my Dell D6000 solved the problem for me as well. But I am a little puzzled over what the update rectified since the firmware is from june last year.

It will keep our communication more focused over one specific case.
