Thank you for your inquiry. The AC Infinity AI-CFD120BA Dual 120 Quiet Cabinet Fan, Black should just turn off and on through the control switch. What your describing sounds like it is turning on and off on its' own. If it properly connected to the wall and the USB is fully plugged into the adapter then this is could be a defective unit. If it turns out that you discover this is defective I want to first apologize for the fan not working properly and start the exchange process for you right away. I'll make a note to the Quality Assurance Department and ensure this doesn't happen again. Here is what I need to send you a UPS Return Label via email to get this product back and initiate the exchange process. To locate all relevant information I need your Amazon Order Number. Also, please confirm your shipping address. As soon as we receive the unit we will ship a replacement via USPS Priority Mail and email you a tracking number. Thank you for giving me the opportunity to help address this matter. Once again, I'm really sorry that this happened. Please let me know if there are any questions or concerns and I'll be happy to help. Thank you and have a great day! Kind Regards,

is it working by USB or not?

Yes! My works well by USB connected to the main unit. I am not sure about stand alone.
