This seems to the a behavior that appears on recent Windows 10 / Windows 11 installation. It is related to some minor change we introduced to improve the monitoring timing for Microsoft standard driver “usbser.sys” devices.

We are currently working on a short-term update to resolve the issue. If the CPU use is a critical issue, you can use the
Docklight V2.3 versions available at our software download archive. (See the link below.)
