This is also the same fault for some reason the usb drivers are not being reconised by the software when you were installing the software were you given a option to save the usb drivers? If so did you create a folder for them ( i always setup a folder called Panasonic directly at the C: root before installing the main software then when asked if i want the usb drivers i just have to pick panasonic from the c: drive when you plug into the phone system does it see the system as a panasonic PBX?
