Detection Error, Bluetooth can't sync cell phones with Laptop

I'm so frustrated, no help desk or phone number to call with my problem. So I hope someone here can help.
I purchased a USB Dongle Cirago BTA-3210, loaded the software from the disc and plugged the bluetooth dongle into the usb port, device drivers were loaded. 2 cell phones I have a new and I bluetooth and visibility turned on. Both phones can find the PC and I'm able to add as a device with a passcode. But go to transfer a file via the file transfer software and it won't work. I then found the devices were not added via the wizard. The wizard can find the phone, but try to make a connection and they can't. I deleted the PC device from the phones but I still have the detection error. Any ideas what is wrong? IS the dongle defective?
