Adapter No Longer Being Recognized Since Upgrading to 2.5 Beta 1

[ourzoo]

I'm running Yosemite 10.10.5 on a 2012 Macbook Pro. I have 2 external monitors, one powered via MiniDisplay Port to DVI and the other Display Link USB to DVI. All were working perfectly until I checked and decided to install the new beta.

Since installed, the Mac no longer recognizes the USB adapter what so ever. I have tried rebooting, uninstalling, correcting permissions, reinstalling, rebooting and still nothing. I have tried reverting back to 2.4.2 and still nothing. I have switched USB ports to make sure it isn't the port and I have even connected the other monitor with my other adapter and it works flawlessly.

Please help, being down a monitor is going to kill my productivity for work.

Now what????????????

Would recovering the system via time capsule do the trick?

Hi ourzoo,

We need logs to understand what's going on. This is completely unexpected as you would imagine...

Can you please follow the instructions here: http://support.displaylink.com/knowledgebase/articles/533818-how-can-i-report-issues-to-displaylink

Best regards,

I tried downloading the tool multiple times and it's downloading as an executable file for Windows and not for Mac. It doesn't matter whether I have Parallels and Windows running or not? The software is installed on the Mac HD so I don't see how sending any logs from Windows would be helpful. Please advise on what to do next?

Nevermind, figured out the issue. Collecting data now and will send over.

This was my exact experience today. I sent an email to Support through the Contact form, and have downloaded the Information Collection tool.

One thing I tried in troubleshooting is looking at the System Report for the Mac, to see if the Diamond BVU 3500 was showing up as a USB device. It is not.

Prior to attempting the upgrade the system was working perfectly.

Many thanks for the quick feedback.

To be on the safe side we are pulling the release. If you have this issue please contact us directly at http://support.displaylink.com

this also happens in the 2.4 release version. We just figured out it was the DisplayLink software during a rebuild. Please release a patched version as soon as you can :( We have a lot of folks using Display Link software and usb ethernet adapters

Hi Banjo,

This issue is not the Ethernet adapter compatibility issue. We think your issue to be fixed in the upcoming 2.5 beta 2.

I hope you folks get this figured out quickly. I'm happy I at least have 3 monitors in my office working, but I work from home 2 days a week usually and I'm now down to 2. This is going to hurt until this gets figured out.

Update - I could not afford to keep my monitor disabled, so I purchased a new Plugable multi-display adapter. I plugged it in with the system shut down and 2.4 installed, and the monitor came up perfectly, runs great.

It appears, as unlikely as that seems to me, that the 2.5 beta1 driver may have actually disabled or damaged the Diamond adapter. Maybe it corrupted the firmware? This is out of my pay scale.

I will contact DisplayLink directly on this as well.

Everything was working perfectly for both of us (others as well I'm sure) Only thing that changed is we installed the beta. At home where I installed the beta, the adapter is toast. In my office, all 3 of my monitors fire up no problem running 2.4. And I should add it's playing nice with El Capitan for now as well.

While I anticipate some bugs in a beta, I don't anticipate losing my device functionality no matter what I try. I'm 100% sure the software disabled the adapter either temporarily or permanently.

Just plugged in my new adapter at home and voila, all is well again (still running 2.4). Thank you Carlo and Wim!
