I am using Windows XP and i believe I am using a USB 2, however not a 100 %.
Follow these steps exactly:
1. Connect the USB cable to the computer.
2. Control Panel --> System --> Hardware tab --> Device Manager. Scroll down to Ports (Com & LPT) and click on the +. Read the line that shows your USB-to-Serial cable and make a note of which ComPort it is. (Should be Com3 or higher.)
3. Close up all the control panel windows.
4. Fire up the CPS and turn the radio on. Remove the mic.
5. Plug the RJ-45 end of the cable into the mic port of the radio.
6. DO NOT click on the button for reading the radio. Instead, on the very top line, click on File and then on Read Device. When you do that, you should get a little window titled Select Port. Use the drop-down to pick the same port that you identified in the Device Manager. Then click OK.
If all goes well, it should read the radio. The very first thing you should do is save a copy of the codeplug. Click on File, and then on Save. Call it whatever you want, but make sure you can identify it as the original working codeplug from the radio.
Now, if it does not work and you still can't read the radio, it's not the end of the line. You'll want to get a serial programming cable for the CDM's and use the serial port on the computer. I had that exact problem with the older Panasonic Toughbook that I just set up for programming. It runs XP Pro and wouldn't recognize the USB cable either. I already had several of the Serial programming cables for these radios so I just switched and it works beautifully.
An odd point is that I also have the Commercial Series CPS on the same computer, and it recognizes the USB programming cables just fine. Weird, but it is what it is.
BTW, the serial programming cable for the CDM's will also program older Motorolas like the GM-300's, SM-50's, M1225's, and a lot more. Something like this should do the trick if you have a DB-9 serial port:
Programming Cable For Motorola Radius Maxtrac GM300 M1225 CDM1250 CM200 CM300 Please note that this listing is the first one I found, and I am not specifically endorsing it. If your computer has a DB-25 serial port, there is a version for that, too.

Series of mobile radios includes:

It may be helpful to search using wildcards.
If someone asks a question about one model,
the answer usually pertains to most, if not all.
They are all programmed with HVN9025 CPS.
The last version of the CPS released before the
product line was discontinued is R06.12.09.
If you need a blank codeplug, there is a folder
full of them, one for each possible model
number on your hard drive. The folder is in
the Program Files where your CPS is installed.
It is labelled SAMPLES.
