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
Windows will usually install the USB Serial Device driver (usbser.sys) automatically. Check in Device Manager under Ports (COM & LPT) . You will see something like USB Serial Device (COM3) .
The VK-172 is a standard USB CDC device. No special drivers are needed in most modern operating systems—just plug it in and read NMEA sentences from the virtual serial port.
ls -l /dev/ttyACM* /dev/ttyUSB* Use cat , screen , or minicom to read NMEA sentences: vk-172 driver
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.
This document explains how to verify, install, and troubleshoot the necessary drivers for the VK-172 on Linux, Windows, and Android. The VK-172 is plug-and-play on most Linux distributions. The kernel includes the cdc_acm driver.

sudo stty -F /dev/ttyACM0 9600 Windows recognizes the VK-172 as a serial-over-USB device. You will see something like USB Serial Device (COM3)
The VK-172 typically runs at 9600 baud (u-blox 7) or 115200 baud (u-blox 8). Use stty :
dmesg | tail -20 You should see output similar to:
Plug in the VK-172 and run:
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 )
