You could try the following:
Disconnect the device from the GPy and measure the current that flows from either output of the device to GND of GPY, with the other device output floating and the GPY's USB port connected to your PC. The current should be 0. If not, the device has internal connections to GND, which can have the effect you see.

I have an Arduino connected to a GPy via serial. The Arduino sends data strings to the GPy. The GPy sends the data to my database at the end.
I have to tell you though, that sending data via LTE-M didn't work reliably for me till I took some certain measures.
Problem 1:
The GPy consistently stopped working for me after a short while (every few days), because of Guru Meditation Errors, where the GPy often completely froze. It just couldn't recover by itself. That's why I've used my Arduino also as an external Watchdog, resetting the GPy with the Arduino. These Guru Meditation Errors seem to come up pretty often while using it to transmit data (LTE-M).
Problem 2:
Sometimes the GPy also thinks it has a data connection, while it is not the case. Using the Reset pin on the GPy doesn't help in this case. That's why I also had to implement a P-Channel Mosfet, which cuts the power off from the GPy. This power cycle helps with the problem in my experience.
The features of Pycom hardware are wonderful, if you are interested in getting your data onto a server, but you have to take some measures to make it work reliably.
I wish you good luck with your project!

If you have both in the same firmware (which you can change), you’ll be able to verify if the difference is due to the firmware (if with the same version they behave the same) or the hardware (if with the same version one is still better then the other).
The issue is that if it turns out to be the firmware which makes the difference, I don’t know if you can revert to the old version.

I noticed you have not received any reply yet, a pattern I think relates to the fact that Pycom's primary focus is on their backend service offering, hardware is just a tool to get there, hence they discourage non Pycom firmware development.
We have just started out on the same road, but still cannot get to flash WiPy or FiPy devices reliably using the PySense and PyTrack boards. Have connected a switch to EN pin and tried 5 different USB adapters, 4 different types. No luck getting any output
But (using  PySense or PyTrack) the devices connect to the dev platform and can be flashed, upgraded and operated.
Any suggestions?
