As you know, the CyResetDevice will cause re-enumeration of the device. To see that what you can do is:
1. In one terminal enter:
tail -f /var/log/syslog
2. In another terminal run an application which opens the device. After opening the device, pass the handle to CyResetDevice API.
By doing that in the other terminal you can see the device being disconnected and getting connected again.
Let me know for further questions.
