Get the latest drivers and update them. Do you have enough RAM? Shut down everything except the system tray and explorer, disable all screensavers and antivirus softs. In short make sure that
the US122 is the only USB device attached and that your recording software is the only application using system resources.
Don't give up, I am having troubles with this device too, it seems that it is very particular with it's configuration needs.
