Power surge on USB Port - Windows 10

[AlbanRampon]

Hello,

This is taking place before the DisplayLink driver is invoked by Windows.
The first step when you connect is to give some power to the device and the device introduces itself to the USB host controller (computer).
Then, based on that introduction, Windows knows which driver to assign.
Because the message states "Unknown USB Device", I gather it did not enumerate (introduced itself) properly.

I suggest you use the Y-cable that AOC is supplying with the monitor and, at least temporarily, try to power that portable display through an externally powered USB hub.

I believe you have a brown out issue. Portable monitors need a lot of power because they need to drive the backlight and panel. The important power draw can be too much for a single port to provide.
If the Windows Update included a DisplayLink driver (I don't remember updating AOC devices lately) or if you changed the DisplayLink driver yourself, the device needs to be reflashed. This may take a minute or two.

Should the issue persists with the additional power, I would be interested in getting the ZIP file created by our Customer Support Tool to look if I can see anything. The third link in my forum signature explains how to gather these.

Kind regards,
Alban
