Unable to Connect With Desktop Manager

[bpellet314]

Hi. I have tried everything to connect to my desktop. When I click on connect the screen is pointing to COM3 but I have the Blackberry plugged into a USB port. I select AUTO detect with no luck. The phone is causing a noise in the PC but always shows disconnected. In OPTIONS I cannot find the Communication Settings option one pop-up wants me to change. What do I do to connect to the desktop manager?
Thanks all.
