Ethnet connectivity (with external nic attached to windows) drops after a while

Hi,
I've connected an external usb-rj45 device to my Macpro m3 and use this to configure devices on a separate subnet using windows applications.
The connection through this device drops after a while, reconnecting the usb brings up the connection.
The connection even dropped yesterday when performing firmware updates through the usb network interface.
I've tried several network interfaces all have the same behaviour

I've followed the troubleshooting steps of reinstalling parallels toolbox and cleaning the msconfig startup services.

I need a stable connection for firmware updates, please help.

Version:
Macbook Pro M3
MacOS Sequoia 15.4
Paralells 20.3.0 (Pro edition)

Edition Windows 11 Pro
Version 24H2
OS build 26100.3775
