I thought so too, but then why would it communicate with the PC? I can read/write without any problems from the scanner to the PC USING THIS CABLE WITH THE PUCK DANGLING OFF THE END. Its obviously not the cable then, but if I can read/write to/from the scanner its probably not the scanner either? Unless the USB data pins are different for the PC comms and for the Serial comms? But I can use my scanner as a serial device (think proscan)... So how can it be an issue with the port?I'd bet it's #2: the radio's USB port.
