Right click the entry and select "Properties". The property window will open. In this window select the Tab "Port settings" and click on the button "Advanced...". If you see a message with the content "You must have write privileges in the registry for this device in order to modify the device's advanced settings.", that means you did not open the device manager as administrator. Close the properties and device manager windows and try again.
If you have adequate rights, the "Advanced Settings for COM[X]" window will open. Under "BM Options", set the "Latency Timer (msec)" to "1".
Click the "OK" button. The advanced settings window will close. In the properties window click the "OK" button again. Again the window will close. Now you can close the device manager. Unplug your device for at least 5 seconds and plug it in again. When connecting to your hardware with CLS2Sim you should now have a slightly improved hardware update rate.
