Here is the text for a VK-172 driver (typically for Linux systems, as the VK-172 is a USB GPS receiver based on the u-blox chipset). Introduction

If it shows as an unknown device, download the u-blox Virtual COM Port Driver from the official u-blox website or use a generic USB CDC ACM driver. The VK-172 is plug-and-play on most Linux distributions

sudo cat /dev/ttyACM0 (Output example: $GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47 )
