I think it has to do with which comp port I'm using. I can't seem to find a port that is not being used already
Did you load the specific serial driver for your scanner? It's not like the older 396XT, where the scanner is set up to use an existing serial port on the pc (or via a USB to Serial adapter, or the Uniden programming cable; That Uniden USB-1 cable is not used for your 325P2.).
The link is near the bottom of this Wiki page:

You can also find the link on this
page from ScannerMaster. Note that the same serial port driver is used for the 325P2, 996P2, as well as the x36HP & SDS series scanners.
