When accessing a COM port, Docklight V2.4 consumes a lot of CPU time (e.g. 25%), even if there is no communication. How can I fix this?

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.)
