The VK-172 is a low-cost, low-power USB GPS dongle that uses a u-blox 7-series or 8-series chipset (often referred to as a "G-mouse"). It does not require a proprietary driver in most modern operating systems because it conforms to the USB CDC ACM (Communications Device Class Abstract Control Model) standard. This means it typically appears as a serial port. vk-172 driver

sudo stty -F /dev/ttyACM0 9600 Windows recognizes the VK-172 as a serial-over-USB device.

ls -l /dev/ttyACM* /dev/ttyUSB* Use cat , screen , or minicom to read NMEA sentences: dmesg | tail -20 You should see output
