I don't know if HITL debugging is supported in Cygwin, but @MaEtUgR will.

@Evaneee I successfully used HITL with the Cygwin toolchain on Windows before.

Make sure the vehicle is in HITL mode with the parameter SYS_HITL
Make sure QGroundcontrol is closed
I think I started HITL with the command ./Tools/jmavsim_run.sh -q -d COM3 -b 921600 -r 250 COM3 is the device I see in your device manager. I'm not sure anymore but I think I had to use the windows naming of the port because it goes through java which is windows native.
As soon as it connected successfully you can open QGC again and do your tests

Sorry I can't currently test but can you try and write if it works?

Awesome. I'm closing this. @MaEtUgR I've added note to the docs - can you please check them? PX4/PX4-Devguide#791
