Motorola

I just got a bluetooth usb adapter for my desktop so I could transfer files between it and my Motorola v551. I can find the phone and all the services that the phone allows, but when I attempt to connect to the phone to transfer files, it tries to connect, but always fails. I am never able to see the files on the phone or anything, but the phone always displays the bluetooth icon, so it seems to be interacting. I turned off my firewall and I have no idea what else to do. Thanks for your help.
