Can you help me connect a usb mic?!

Hi everyone, this really destroys my confidence but I cannot get the usb mic to work in cubase 8.5. I created a bus in the connections, did everything I could think of in the device setups, but there is no signal. I think i must be missing something. Please could anyone be detailed on the steps to follow?
Thanks ever so much.

It’s usually the case that you have to install ASIO4all driver on Win to use a USB mic in a ASIO application.

Thank you very much both of you!!
