I had that same issue when I was connecting my HT1250 to Windows 10. I changed to Windows XP on an old laptop with a serial port and it worked great. I got a program cable with a serial connector on one end. Everything works great. Only took me an hour to setup my  radios the way I wanted them.

You need a proper RIB and Motorola mobile radios cable and the software running on a PC with a true RS232 port.. The USB stuff is for the birds.
