GPS Data Logger Software - BT747

Hi,

I already received my gps 747a+, I charged it and used to get some coordinates.

Now I installed the BT747 software, but I can not even detect the device. The drivers from the supplier are installed, and the MAC Bluetooth can detect the device, but despite of it... I can't access via Bluetooth neither USB.

I don't know anything about the commands I have been reading here in previous threads, how to detect which USB port is taking the GPS connected to the USB... I would like to recieve some help.

Thank you very much in advance!
