Yup they do. I just plugged it in.
Right, I started everything up and the unit was unrecognised as you said. Interogated Windows a bit and it said there was a problem with the driver. Shut down and restarted Windows and it was happy.
Started mapsource and had to go to; Tools, Get unit ID, click on USB, OK. After that the 76 ID was read by Mapsource and everything is hunky-dory.
You have clicked on Start Tracking under the GPS tab....of course you have.
Hope this helps.
Edit: Don't know about the 72 but, with the map76 if you go to the setup menu, interface, then it will tell you whether it is speaking to the USB or not.
