I'm not talking about how winblows or linux numbers the port. I'm
talking about how u-blox numbers the ports.
I find every reset will toggle the u-blox on linux from ACM0 to ACM1 and
back.

2 hours, and zero results is bad. AHve you upgraded any F9P

None of which tells me which u-blox port the xbee is on.

Good luck. GPS only may not be too bad.
