Hello,
There is a very good reason why the audio and Ethernet drivers are packaged with the rest. If versions don't match then things can't talk to each other...
The version 7.9.1612.0, is the package build, not the version of the driver it includes. Manufacturers like Dell decides of options they want in the docks they make, and the branding of the installer. That's why the package build number is different than the generic package you have from our site. Inside is the same: 7.9.1589.0 USB driver and host software (you can look at the release notes).
You mention "connecting a mouse to DisplayLink". This is impossible physically. DisplayLink chip cannot host devices. You connect your mouse to a USB hub in the dock. That USB hub is not DisplayLink. The DisplayLink chip is also connected to that hub. DisplayLink does not make any hub, adapter or dock, and DisplayLink driver cannot command the USB hub, or any device connected to it because Windows decides the driver to use based on the device I'd.
Should you decide to keep 7.9 M7, you will get severe failures when the new Intel/nvidia graphics driver are pushed to your machine. This is a promise, we and Microsoft have tested. You may not be able to login.
The help documentation is not really relevant to Redstone builds. As we use native OS support, we are limited by what we can do compared to before.
Are you in Replace, Clone or Extended desktop?
There is a Windows bug in Replace mode: Windows puts the graphics card to bed so it stops calculating pixels. The OS still uses the graphics card to compute the pixels to send to DisplayLink.
Can you reproduce the issue after uninstalling the primary graphics card driver and using the Microsoft Basic Graphics inbox driver?
What applications are running when you have the issue?
Is the issue addressed by a dock replug?
Is the D1000 connected in USB2 or USB 3?
I'm asking these questions to understand the root cause as we haven't noticed that yet and we need to get it to debug it... And I clearly don't get it , yet
We had a bug on recovery from sleep, this is fixed in 8.0.629.
If several versions of DL are installed at the same time (7.9 being installed over 8.0), they might have a duel.
Kind regards,
Alban
