To do this, open the Windows control Panel and start the device Manager from it (it is in the Hardware and Sound group). In device Manager, expand the USB Controllers group and verify that the USB Serial Converter device is listed.

If instead, there is a device named "Serial -> USB", it means that ECG device may be damaged by static electricity. To restore it use "Recover ECG module".

Next, right-click on this item and select "Properties" in the menu that opens. The device properties window opens. Make sure that the "Device status" field says "Device is working fine", then switch to the "Driver" tab and make sure that the version of the installed driver is "" or greater.
