Most of these issues could be the driver didn’t install completely or your laptop had already included other Silicon version driver to conflict, therefore the laptop can’t recognize the GPSport245 device.
- First, Holux would suggest try to change another USB port or laptop to connect the GPSport 245 by USB cable when it is powered off. After that you can check out whether the problem still persists, if it still doesn’t work please try to use the second solution below.
- Please review the “Add / remove program” items on your laptop, and remove all of driver files that the first name has show the “Silicon Lab…..”, then restart your computer and try to re-install the driver.You could download the driver from our website:

After installing the driver,please try to connect GR-245 with your laptop again and check again.
