no doubt it is older but could give you some help.

I also read example for setting up the C01U in MAC OS X in Owner's Manual. It says

Windows
1. The first time you plug the C01U Pro into a USB port, Windows will install the
universal USB drivers for that port.
2. To set the C01U Pro as your default input/recording device, or to change
its settings, open the Control Panel, Hardware & Sound settings, then click
SOUND. Under Recording tab, you can select the Samson C01U Pro from the
list of devices and press the Set Default button to set it as the default audio
input device.
3. To set the gain of the microphone, click the Properties button, and then select
the Levels tab. Slide the control until the desired level is reached. If you Find
that the microphone red clip LED is lighting frequently, turn this control down
until the LED no longer flashes red.
4. To set the headphone level, select the Playback tab, open the C01U Pro
Properties, then select the Level tab and adjust the computer’s Master Volume
slider.
5. To turn direct monitoring on or off, open the Speaker Properties, select the
Level tab, then click the Microphone speaker icon.
