Hi RNP,
Certainly!
If you want to prevent the modem from auto-installing, you'll need to go into Device Manager from the Windows Control Panel, expand the "USB Host Controllers" category, and then right-click and "disable" the USB Mass Storage Device. This will then prevent the modem from auto-installing - however, you must remember to always use the same USB port, or you'll need to repeat this action for every port on your machine.
I trust this helps
