Most can do GPS over Wifi or BT with no additional hardware required other than a smartphone and their Pi (or other computer).
GPSD forwarder is a free Android app that makes it possible for Android and Linux. It's a bit more of a pain for Windows and requires a bit more effort but can be done with some GPS drivers on the Windows side and the Bluetooth GPS output app on the phone.?

If the USB port is giving grief, why not ditch it and try something like serial over BT or WiFi?

Here is a Serial to WiFi gadget built using an esp8266.

I run OpenPlotter, open source navigation software, on a RPi 3 using BT in place of serial.? The BT serial SPP connection appears? as a /dev/rfcomm0 virtual serial port.? OpenPlotter opens /dev/rfcomm0 which looks exactly like a serial port. This wireless connection? works quit well.? No issues.?
