Vesc problems connecting

[ClintBarton]

Hi,

I tried to connect my Vesc to my computer using a cable. It makes that sound sating that its connected but when I go on BLDC tool, and try to connec, it says Device not Found. Does anyone out there know how to fix this.
Do I have to connect my motor to the Vesc when planning on configuring it?
Is this a Vesc problem or Computer problem?

Please help. 

I didn't find the right solution from the Internet.
