Having problems using your USB adapter?

Problem: I can't transfer any data, or my map software doesn't see the USB adapter.

The most common issue when installing the USB adapter and driver is selecting the correct port for your map software to recognize.

You must make sure your particular software is looking on the correct port for it to transfer any data.

To see which port your USB adapter is connected to, connect your USB adapter and follow the following instructions:

  1. Go to the Start Menu
  2. Right click on "My Computer"
  3. Select "Properties"
  4. Click on the "Hardware" tab
  5. Click on "Device Manager"
  6. Click the + sign next to "Ports (COM & LPT)"
  7. One of the listed ports should indicate which port your USB adapter is connected to (e.g. COM1, COM2, COM3, etc.)
  8. Go back to your map software program that you use to transfer data and make sure it is looking at the correct port.
  9. You should be able to transfer data once the correct port is selected
