Hello,
There are some incoherence reported, and it makes it more complex to understand.
Your Device Manager view reports that there is a DisplayLink Network Adapter NCM with proper drivers.
However, when you look at all the network cards present with an ipconfig/all, the DisplayLink one is absent and
all cards are disconnected.
The reason for that would be if your DL card was deactivated in your Device Manager, but I can see this is not the case.
I can see some issues on your USB communication during the enumeration of the network card. (that's the part where everyone introduces themselves on the USB: "Hello, I'm DL Ethernet and you can fetch my drivers as VID_17E9&PID_4305".
To put aside any installation corruption, I would like you to use our installation cleaner. This will make sure nothing is left behind and you can do a clean reinstall using 7.9M3.
Once you have done this, I would need a new log files to see if there are any more complaints in them.
KB724494 - Cannot upgrade or uninstall DisplayLink software
Would that be possible?
